CD74HCT123E TI Monostable Multivibrator | 16-PDIP | Dual, Schmitt-Trigger Inputs

Product Overview

The CD74HCT123E is a dual retriggerable monostable multivibrator from Texas Instruments, featuring Schmitt-trigger inputs for noise immunity. It is designed for high-speed CMOS logic with TTL compatibility, operating from 4.5V to 5.5V. The device provides two independent monostable circuits with active-low and active-high trigger inputs, as well as a reset function. Output pulse width is controlled by external resistors and capacitors, offering flexibility for timing applications. Housed in a 16-pin PDIP package, it is suitable for through-hole PCB assembly.
