SN74121D TI Monostable Multivibrator | 14-SOIC | 30ns Propagation Delay, 5V Supply

Product Overview

The SN74121D is a monostable multivibrator from Texas Instruments, designed for pulse generation and timing applications. It features a single-shot output with a pulse width determined by external timing components (R and C). The device operates from a 5V supply and offers a typical propagation delay of 30ns. Housed in a 14-pin SOIC package, it is suitable for surface-mount assembly and space-constrained designs.
