CD74HC423E TI Monostable Multivibrator | 16-PDIP | Dual, Retriggerable

Product Overview

The CD74HC423E from Texas Instruments is a dual retriggerable monostable multivibrator designed for high-speed CMOS logic systems. It features two independent multivibrators with Schmitt-trigger inputs for noise immunity. Each section can be triggered by either the rising or falling edge of an input signal, and the output pulse width is controlled by external resistors and capacitors. The device operates over a wide voltage range of 2V to 6V and is available in a 16-pin PDIP package, making it suitable for through-hole PCB assembly.
