U74HC123 - DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATOR
CMOS IC The U74HC123 is high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL).
The U74HC123 is a dual retriggerable monostable multivibrator with output pulse width control by three methods.
The basic pulse time is programmed by selection of an external resistor
U74HC123 Features
* 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
