CD74HC123NS TI Monostable Multivibrator | 16-SO | High-Speed CMOS, Dual Retriggerable

Product Overview

The CD74HC123NS is a high-speed CMOS dual retriggerable monostable multivibrator from Texas Instruments. It features two independent multivibrators with Schmitt-trigger inputs for noise immunity. Each multivibrator has an active-low trigger (A) and an active-high trigger (B) inputs, along with a clear (CLR) input. The output pulse width is controlled by external resistors and capacitors. This device is ideal for pulse shaping, timing delays, and frequency division in various electronic systems.
