CD74HC123NSR TI Monostable Multivibrator | 16-SO | Dual, High-Speed CMOS

Product Overview

The CD74HC123NSR is a dual retriggerable monostable multivibrator from Texas Instruments, fabricated using high-speed silicon-gate CMOS technology. It is designed for applications requiring precise pulse generation with minimal external components. The device features two independent monostable circuits with Schmitt-trigger inputs for noise immunity. Each circuit can be triggered by either a rising or falling edge, and the output pulse width is controlled by external resistors and capacitors. The CD74HC123NSR operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial systems. It is offered in a 16-pin SOIC package (NSR suffix) for space-constrained designs.
