74HC123-Q100; 74HCT123-Q100 Dual retriggerable monostable multivibrator with reset Rev. 2 — 19 January 2015 Product data sheet 1. General description The 74HC123-Q100; 74HCT123-Q100 are high-speed Si-gate CMOS devices and are pin compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC123-Q100; 74HCT123-Q100 are dual retriggerable monostable multivibrators with output pulse width control by three methods: 1. The basic pulse is defined by the selection of the external resistor (REXT) and capacitor (CEXT). 2. 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).
