SN74LS123NS TI Monostable Multivibrator | 16-SO | Dual, Retriggerable

Product Overview

The SN74LS123NS is a dual retriggerable monostable multivibrator from Texas Instruments, designed for pulse generation and timing applications. Each multivibrator features a negative-edge trigger input, a positive-edge trigger input, a clear input, and complementary outputs (Q and Q̅). The device can be retriggered to extend the output pulse duration, and the output pulse width is controlled by external resistors and capacitors. Housed in a 16-pin SOIC package, it operates over a wide supply voltage range of 4.75V to 5.25V.
