DESCRIPTION

The M74HC123 is an high speed CMOS

MONOSTABLE MULTIVIBRATOR fabricated with

silicon gate C

There are two trigger inputs, A INPUT (negative

edge) and B INPUT (positive edge). These inputs

are valid for slow rising/falling signals, (tr=tf=l sec).

The device may also be triggered by using the

CLR input

Schmitt-trigger input; after triggering the output

maintains the MONOSTABLE state for the time
