Title: Semiconductor device
Inventor: OKIDAKA TAKENORI
IPC: H01L27/088
Filed: 1987-06-23
Abstract: PURPOSE:To prevent the malfunction of a semiconductor device, by using an npn-bipolar transistor as the transistor to be connected with the high-potential power source side of the output section and providing an n-channel MOS transistor, whose drain is connected with the input terminal and source and gate area connected to a lowpotential power source. CONSTITUTION:Since an npn-bipolar transistor Q5 is connected with the high- potential power source side of an output section, no parasitic diode is formed between the collector and emitter of the transistor Q5. Therefore, such a trouble that a semiconductor device with a three-state output wrongly operates when the power supply is turned off never takes place. Moreover, since an-channel MOS transistor Q8 is connected with an input section and the substrate area, in which the MOS transistor Q8 is formed, is connected with a GND terminal 3, a parasitic diode 21 is formed between the drain of the transistor Q8 and GND terminal 3 and a high static destruction resisting pressure is given to the input section by the action of the MOS transistor Q8. Therefore, the malfunction is prevented.

Abstract: PURPOSE:To reduce cost while making static electricity easy to escape by providing a resistor, which is connected between a connection point of two diodes connected serially in the same direction and a switch, and an input circuit while having a different power supply system from the diodes. CONSTITUTION:One piece each of diodes 5 and 6 are provided between a switch 1 and power supply 8 and 9, and a resistor 10 is provided between a contact point between the diodes 5,6,and an input circuit 7. Static electricity from the switch 1 escapes to the diodes 5 and 6 having low impedance than to a resistance path 10 having high inpedance. Then, since power supply V is surrounded by things, which absorb static electricity or the like such as capacitors, static electricity travels power supply lines 8 and 9 to be absorbed by the power supply V. Accordingly, destruction of an input circuit due to static electricity of human body to be impressed at the time of operating the switch 1 can be prevented while reducing cost. Further, Since there is no resistor between the switch 1 and the diodes 5, 6, static electricity or the like is easy to escape.
