74HC123D - Monostable Multivibrator, SMD IC

The 74HC123D is a dual retriggerable Monostable Multivibrator with reset and output pulse width control. This is high-speed Si-gate CMOS devices and are pin compatible with low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard number 7A. Schmitt-trigger action in the nA and nB inputs, makes the circuit highly tolerant to slower input rise and fall times.
