U74HC123 Description
CMOS IC The U74HC123 is high-speed Si-gate CMOS device and is pin patible 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 (REXT) and capacitor (CEXT).
U74HC123 Key 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
