Texas Instruments TPUL1G113-Q1 Monostable Multivibrator

Texas Instruments TPUL1G113-Q1 Monostable Multivibrator is a single RC configurable retriggerable monostable multivibrator designed for operation from 1.5V to 5.5V. By selecting external resistance and capacitance values such that the output pulse width is approximately tw = R × C, the output pulse duration can be configured.

The Texas Instruments TPUL1G113-Q1 features three trigger inputs, allowing for falling-edge (T) and rising-edge (T) triggers, and a clear input (CLR) that can be used asynchronously to stop an active output pulse, forcing the output low and resetting the device. All trigger inputs use a Schmitt-trigger architecture to accommodate slow input transition rates and improve noise immunity.
