SL74HC123 Datasheet (System Logic Semiconductor) - Dual Retriggerable Monostable Multivibrator

SL74HC123, Dual Retriggerable Monostable Multivibrator

SL74HC123 Dual Retriggerable Monostable Multivibrator The SL74HC123 is identical in pinout to the LS/ALS123.

The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.

There are two trigger inputs, A INPUT (negative edge) and B INPUT (positive edge).

These inputs are valid for rising/falling signals.

The device may also be triggered by using the CLR input (positiveedge) because of the Schmitt-trigger input; after triggering th
