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.
