3 Description

The TPUL2T123-Q1 device contains two independent RC-configurable retriggerable monostable multivibrators designed for operation from 1.5V to 5.5V. Configure the output pulse duration by selecting external resistance and capacitance values with an approximate output pulse width of two ≅ R × C.

This device features three trigger inputs, allowing for rising edge (T) or falling edge (T) triggers and a clear input (CLR) used asynchronously to stop an active output pulse. All trigger inputs include Schmitt-trigger architecture to allow for slow input transition rates and improve noise immunity.
