Title: Electrostatic protective circuit
Inventor: ITO MASA
IPC: H01L23/556
Filed: 1990-10-08
Abstract: PURPOSE:To prevent deterioration of a protective function due to impedance of a power supply line by a method wherein, when a surge voltage is applied, a base and an emitter in an NPN transistor are shorted by a parasitic bipolar transistor. CONSTITUTION:A terminal 11 is connected to a cathode of a diode 12 and an emitter of an NPN transistor Tr 13 and further to a P type diffusion region. When, at the terminal 11, a potential of a power supply terminal 15 rises by an on-voltage BE of a parasitic PNP Tr 21 by a surge voltage, the Tr 21 is on. Next, a surge current Is flows from the terminal 11 to a collector side of the Tr 21 and escapes to a GND through impedance Z1. In this embodiment, when the impedance Z1 is high, or when the current Is is high, the Tr 21 is saturated by a voltage (Z1XIs) produced at the impedance Z1. Thus, a base and an emitter of the Tr 13 are shorted, the current Is is absorbed to accurately protect a junction between the base and the emitter of the Tr 13, and deterioration of a protective function due to the impedance of a power supply line 19 can be prevented.

In this case, the control section 3 sends the same data for N times. The data received by a reception section 4 are stored in a buffer 5 at the receiver side and a check section 8 discriminates the presence of an error. When data of the same serial number having no error are received for n-times, the data are received. In this case, data of a serial number control section 7 are updated. When data with other serial number are received within the reception of n-times, the data are aborted as error correction disable data and data of the control section 7 are updated.
