The 74HCT123N is a dual retriggerable Monostable Multivibrator with reset is a high-speed Si-gate CMOS devices and are pin compatible with low-power Schottky TTL (LSTTL ). The device is specified in compliance with JEDEC standard no-7A. Schmitt-trigger action in the nA and nB inputs, makes the circuit highly tolerant to slower input rise and fall times.
DC triggered from active high or active low inputs
Retriggerable for very long pulses up to 100% duty factor
Direct reset terminates output pulse
Schmitt-trigger action on all inputs except for the reset input
