SN74LS123DR TI Monostable Multivibrator | 16-SOIC | Dual, Retriggerable

Product Overview

The SN74LS123DR is a dual retriggerable monostable multivibrator from Texas Instruments, designed for generating precise output pulses of variable duration. Each multivibrator features a negative-edge trigger (A) and a positive-edge trigger (B) inputs, along with a clear (CLR) input for resetting the output. The output pulse width is determined by external timing components (R_ext and C_ext). This device is housed in a 16-pin SOIC package, making it suitable for space-constrained applications.
