SN74LS122NSR TI Monostable Multivibrator | 14-SO | 50ns Propagation Delay

Product Overview

The SN74LS122NSR is a retriggerable monostable multivibrator from Texas Instruments, designed for generating precise output pulses of variable duration. It features two trigger inputs (A and B) and a clear input for resetting the output. The device is fabricated using Schottky-clamped TTL technology, offering a typical propagation delay of 50 ns and a maximum output pulse width of 40 ns. It is housed in a 14-pin SOIC package (NSR suffix) and operates over a supply voltage range of 4.75 V to 5.25 V. This device is ideal for applications requiring pulse shaping, timing delays, and frequency division.
