The TPUL2T323 device contains two independent extended-pulse-width RC-configurable retriggerable monostable multivibrators designed for 1.5V to 5.5V operation. The output pulse duration is configured by selecting external resistance and capacitance values with an approximate output pulse width of two ≅ 1000 × R × C.

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