Abstract

PURPOSE:To reduce the number of pins and to achive low cost, by commonly using the input and output pins through the positive feedback from the signal given at the input to the input further. CONSTITUTION:The first and second terminal 29 and 30 in common connection of input and output are provided. After the application of power supply B, while input is not given, although the first and second latch circuits 100 and 101 are turned off, if the first input switch 14 is turned on for a short time, the circuit 100 is ON and the potential at the terminal 29 is from BV to 0. Positive feedback on the transistor TrQ7 is made and the circuits 100 and 101 respectively keep ON and OFF. Next, when the second switch circuit 15 is ON for a short time, the circuit 100 is OFF and the circuit 101 is ON, the terminal 30 is from BV-0V. Positive feedback is made to the input TrQ8 and the circuits 100 and 101 keep respectively OFF and ON.
