Net Income per Share Basic EPS is computed as net income divided by the
weighted average number of common shares outstanding for the period.  Diluted
EPS reflects the potential dilution that could occur from common shares
issuable through stock options, warrants, and other convertible securities.
The following is a reconciliation of the numerator (net income) and the
denominator (number of shares) used in the basic and diluted EPS calculations.

Note 4
------

Comprehensive Income The Company has adopted the provisions of Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income",
effective April 1, 1998.  The statement requires the disclosure of
comprehensive income and its components on the Statement of Income or in a full
set of general-purpose financial statements.  Comprehensive income is defined
as net income plus revenues, expenses, gains and losses that, under generally
accepted accounting principles are excluded from net income.  For the quarter
ended September 30, 1998 and 1997, comprehensive income approximated net
income.

      
PART I - FINANCIAL INFORMATION

Item 2 - Management's Discussion and Analysis of Financial
	 Condition and Results of Operations

Certain Factors: This report contains forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933
and Section 21 E of the Securities Exchange Act of 1934.  Actual
future results could differ materially from those discussed here
and elsewhere in this report.  Factors that could affect future
results include general economic conditions, both in the United
States and foreign markets, economic conditions specific to the
semiconductor industry, the Company's ability to introduce new
products, its ability to enhance existing products, its ability
to meet the continually changing requirements of its customers,
its ability to manufacture efficiently, its ability to control
costs, and its ability to maintain and enhance relationships
with its assembly and test subcontractors and independent
distributors and sales representatives.


Results of Operations

Net Sales: Net sales for the quarter ended September 30, 1998
were $12,650,000, a 7% decrease from $13,613,000 of the same
quarter last year.  The sales decline was primarily due to price
concessions given to our foreign customers for large exchange rate
differentials and also due to slower sales in our digital integrated
circuit family.  For the six months ended September 30, 1998, net sales
declined slightly by 1% to $25,651,000 from $25,925,000 when compared
with the same period of the prior year.

In this quarter as well as the six months period, approximately 56% of
the Company's net sales were derived from customers outside the United
States.  All of the company's sales to international customers were
denominated in U.S. currencies.

Gross Margin:  As a percent of sales, the Company's gross margin for
the quarter and the six month periods ended September 30, 1998 increased
to 49% and 48% respectively, compared with the 45% gross margin for the
same quarter and six month periods of last fiscal year, primarily due to
cost control measures taken.
  
Research and Development:  Research and development expenses increased
to 12% of net sales for the quarter and six months ending September 30,
1998.  This compares with R&D expenses of 11% of net sales for the same
quarter and six month periods of last year. Dollar expenditures increased
slightly to $1,478,000 and $2,979,000 for the quarter and six months ended
September 30, 1998 respectively, as compared with $1,425,000 and $2,801,000
for the same periods of the last fiscal year.  The increase was related to
new product development and the Company expects that new product
development expenses will continue to increase during this fiscal year.

Selling, General and Administrative: Expenses for selling, general and
administrative were higher at $1,785,000, or 14% of net sales as compared
with $1,603,000, or 12%, in the same quarter of  last fiscal year.  For
the six months ended September 30, 1998, selling, general and
administrative expenses were at 14% of net sales compared to 13% for the
same period last year.  The percentage increase in this category was due
to an increase in bad debts expense.


Interest Income: Interest income for this quarter were $483,000 compared
with $373,000 last year.  Six months interest income was $953,000, a 33%
increase from $717,000 of the same period of last fiscal year.  Higher
amount of funds available for investments contributed to this increase.

Provision for Income Taxes: The Company's effective tax rate for the
three- and six- months ended June 30, 1998 remained at 34%, same as last
fiscal year.

Overview: Total assets grew to $69,698,000 as of September 30, 1998, up
from $66,629,000 from quarter ending March 31, 1998.  The increase is due
to favorable operating results for the quarter.

Liquidity and Capital Resources  On September 30, 1998, the Company had
$36,816,000 in cash, cash equivalents, and short term investments, compared
with $31,512,000 on March 31, 1998.  This increase is mostly due to positive
cash flow from operating activities of $6,694,000 consisting principally of
net income of $4,417,000.  Net cash used in investing activities as of the
second quarter of fiscal year 1999 was $14,942,000 compared to $7,478,000
for the same period last year.  Net cash used in short-term investment
activities totaled $13,931,000, and $1,011,000 was used in the purchase of
equipment.  Net cash used in financing activities was $481,000.  Repurchase
of stocks accounted for $563,000, which was offset by proceeds from stock
option exercises of $82.  The Company anticipates that available funds and
cash expected to be generated from operations will be sufficient to meet cash
and working capital requirements through the end of fiscal year 1999. 

Year 2000 Compliance Risks: The Company is aware of the issues associated
with the programming code in existing computer systems and software products
as the millennium (year 2000) approaches.  The "year 2000" problem is
pervasive and complex, as virtually every computer operation will be
affected in the same way by the rollover of the two digit year value to 00.
The issue is whether computer systems will properly recognize date-sensitive
information when the year changes to 2000.  Systems that do not properly
recognize such information could generate erroneous data or cause a system
to fail.  As a result, many companies' software, computer systems and other
equipment may need to be upgraded or replaced in order to comply with such
"Year 2000" requirements.

The Company is utilizing both internal and external resources to identify,
correct or reprogram, and test the systems for year 2000 compliance.  It has
initiated its Year 2000 compliance program and has completed the process of
identifying the programs and systems that could be affected by the Year 2000
issue. The Company has also developed an implementation plan to address the
potential exposures related to the impact of the millennium. This plan
includes modification or conversion of certain existing systems with new
systems in order to comply with such "Year 2000" requirements.  It is
expected that the evaluation, remediation, and testing of all necessary
modifications for compliance will be completed by December 31, 1999. The
financial impact of making the required systems changes cannot be known
precisely at this time while the total cost of Year 2000 systems assessments
and modifications will be funded through cash flows from operations.  Based
upon its evaluation to date, the Company believes that the Year 2000 issue
will not have a material impact on the operations of the Company.  However,
if such modifications and conversions are not made, or are not completed in
a timely fashion, the Year 2000 issue will have a material adverse effect
on the Company's operations, business, financial condition and operating
results.

The Company has relationships with, and is to varying degrees dependent upon,
a large number of third parties that provide information, goods and services
to the Company. If significant numbers of these third parties experience
failures in their systems or equipment due to Year 2000 non-compliance,
it could materially adversely affect the Company's ability to process
transactions, manufacture products, or engage in similar normal business
activities.  While some of these risks are outside the control of the
Company, the Company has initiated formal communications with all its
primary vendors and service providers to determine if plans are being
developed or are already in place to address processing of transactions
in the year 2000.  Meanwhile, the Company's net sales could be materially
adversely affected if the Company's customers or potential customers
reallocate spending from the Company's products to their efforts to resolve
the Year 2000 issue.
