HD74HC123A
Dual Retriggerable Monostable Multivibrators (with Clear)
Description
This multivibrator features both a negative, A, and a positive, 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
HD74HC123A can be triggered on the positive transition of the clear while A is held low and B is held
high.
The HD74HC123A is retriggerable. That is it may be triggered repeatedly while their outputs are
generating a pulse and the pulse will be extended.
Pulse width stability over a wide range of temperature. The output pulse equation is simply: t
w
= (Rext)
(Cext).
