SN74LS122DR TI Monostable Multivibrator | 14-SOIC | 50ns Propagation Delay

Product Overview

The SN74LS122DR from Texas Instruments is a retriggerable monostable multivibrator designed for generating precise output pulses of variable duration. It features a single-shot pulse generation with an external resistor and capacitor controlling the pulse width. The device is housed in a 14-pin SOIC package, making it suitable for space-constrained applications. With a typical propagation delay of 50ns and a wide supply voltage range of 4.75V to 5.25V, it offers reliable performance in digital systems.
