The TPUL2T122x devices contain two independent RC configurable retriggerable monostable multivibrators designed for operation from 1.5V to 5.5V. The output pulse duration is configured by selecting external resistance and capacitance values with an approximate output pulse width of two ≅ R × C.
The TPUL2T122x devices feature two trigger inputs, allowing for rising edge (T) and falling edge (T) triggers. Each channel also includes 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.
