MM74HC123A
Dual Retriggerable Monostable Multivibrator
General Description
The MM74HC123A high speed monostable multivibrators
(one shots) utilize advanced silicon-gate CMOS technol-
ogy. They feature speeds comparable to low power Schot-
tky 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 MM74HC123A
can be triggered on the positive transition of the clear while
A is held LOW and B is held HIGH.
The MM74HC123A is retriggerable. That is it may be trig-
gered repeatedly while their 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.
