SN74LS221D TI Dual Monostable Multivibrator | 16-SOIC | 45ns Propagation Delay

Product Overview

The SN74LS221D is a dual monostable multivibrator from Texas Instruments, featuring two independent circuits with Schmitt-trigger inputs for noise immunity. Each multivibrator provides a single output pulse of programmable width determined by external timing components (R and C). The device operates from a 5V supply and is characterized for operation from 0°C to 70°C. Housed in a 16-pin SOIC package, it is ideal for pulse shaping, delay generation, and timing applications in industrial and consumer electronics.
