MM74HC423A
Dual Retriggerable Monostable Multivibrator
General Description
The 74HC423A high speed monostable multivibrators (one
shots) utilize advanced silicon-gate CMOS technology.
They feature speeds comparable to low power Schottky
TTL circuitry while retaining the low power and high noise
immunity characteristic of CMOS circuits.
Each multivibrator features both a negative, A, and a posi-
tive, B, transition triggered input, either of which can be
used as an inhibit input. Also included is a clear input that
when taken LOW resets the one shot. The MM74HC423A
cannot be triggered from clear.
The MM74HC423A is retriggerable. That is, it may be trig-
gered repeatedly while its outputs are generating a pulse
and the pulse will be extended.
Pulse width stability over a wide range of temperature and
supply is achieved using linear CMOS techniques. The out-
put pulse equation is simply: PW
=
(R
EXT
) (C
EXT
); where
PW
is in seconds, R is in ohms, and C is in farads. All inputs
are protected from damage due to static discharge by
diodes to V
CC
and ground.
