Product Summary

The 74AHCT123APW is a Dual retriggerable monostable multivibrator with reset. It is pin compatible with Low power Schottky TTL (LSTTL). The74AHCT123APW is specified in compliance with JEDEC standard no. 7A. The basic pulse time is programmed by selection of an external resistor (REXT) and capacitor (CEXT). Once triggered, the basic output pulse width may be extended by retriggering the gated active LOW-going edge input (nA) or the active HIGH-going edge input (nB).
