Though available in a variety of packages, all devices contain the same silicon chip design. The iGPIB9914A chip accepts the clock signal of the original TMS 9914A. A built-in PLL circuit converts the input to internally used 30MHz clock. After reset, the chip behaves exactly as 9914. Customers who are interested in switching between TMS9914, NEC7210C and enhanced M4882 modes are invited to take a closer look at the iGPIB72010 in QFP80 package . Both existing software for the TMS9914A chip can be run without changes and new designs take advantage of the FIFO buffer and the 488.2 extensions.
Modes are switchable by software.
Home More Top Basic features Drop-in compatible CMOS replacements for the original TMS9914A NMOS device . Works with any application software written for these chips. Single chip solution for GPIB interfaces . Full synchronous chip design ensures proper chip timing for highest reliability. Integrated GPIB line drivers obsolete the use of the discrete 75161 or 75162 type line drivers, which will make the iGPIB series the most cost-effective solution for existing and new GPIB designs.
