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) (CEXT); 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 VCC and ground.
Features
s Typical propagation delay: 40 ns
s Wide power supply range: 2V–6V
s Low quiescent current: 80
A maximum (74HC Series)
s Low input current: 1
A maximum
s Fanout of 10 LS-TTL loads
s Simple pulse width formula T
= RC
s Wide pulse range: 400 ns to
∞ (typ)
s Part to part variation:
±5% (typ)
s Schmitt Trigger A & B inputs allow rise and fall times to
be as slow as one second
Ordering Code:
Note 1: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
