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

* ORDERING INFORMATION Ordering Number Lead Free Halogen Fr
