DESCRIPTION

The M54HC123 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 (positive-edge)

Schmitt-trigger input; after triggering the output

maintains the MONOSTABLE state for the time

period determined by the external resistor R

capacitor C

the output pulse width value is approximately

given by the formula: t

(K 0.45) .

Taking CLR low breaks this MONOSTABLE

STATE. If the next trigger pulse occurs during the
