Product Summary
The HD74HC123AP is a Dual Retriggerable Monostable Multivibrator. The HD74HC123AP 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 HD74HC123AP can be triggered on the positive transition of the clear while A is held low and B is held high. The HD74HC123AP is retriggerable. That is it may be triggered repeatedly while their outputs are generating a pulse and the pulse will be extended.
