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.

The 14-24-LOGIC-EVM evaluation module (EVM) is designed to support any logic device that is in a 14-pin to 24-pin D, DW, DB, NS, PW, DYY or DGV package,
This EVM enables users to evaluate TPUL devices without requiring the soldering of the devices to the board. Users can visualize the footprint and size differences for K = 1 and K = 1000 devices. This board comes pre-configured with equal pulse widths for the standard and extended pulse width TPUL (...)
