DESCRIPTION

The M54/74HC423/423A are high speed CMOS

MONOSTABLE multivibrators fabricated with

silicon gate C²MOS technology.

They achieve the high speed operation similar to

equivalent LSTTL while maintaining the CMOS low

power dissipation. There are two trigger inputs, A

INPUT (negative edge) and B INPUT (positive

edge). These inputs are valid for rising/falling

signals, (t_r– t_f– 1 sec). After triggering the output

maintains the MONOSTABLE state for the time

period determined by the external resistor Rx and

capacitor Cx.

Two different pulse width constant are available:

0.46 for HC423

1 for HC423A.

Taking CLR low breaks this MONOSTABLE

STATE. If the next trigger pulse occurs during the

MONOSTABLEperiod it makes the MONOSTABLE

period longer. Limit for values of Cx and Rx :

Cx : NO LIMIT

Rx : V_CC< 3.0 V 5 K Ω to 1 M Ω

V_CC≥ 3.0 V 1 K Ω to 1 M Ω

NC =

No Internal

Connection

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
