Overview
TECHNICAL DATA
IN74HC123A
Dual Retriggerable Monostable Multivibrator
The IN74HC123A 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 the output maintains the MONOSTABLE state for the time period determined by the external resistor RX and capacitor CX.
Taking CLR low breaks this MONOSTABLE STATE.
