3 Description
The TLV181x and TLV182x are a family of 40
Volt single, dual and quad channel comparators
with multiple output options. The family offers railto-
rail inputs with push-pull or open-drain output
options. The family has an excellent speed-to-power
combination with a propagation delay of 420 ns with
a full supply voltage range of 2.4 V to 40 V with a
quiescent supply current of only 5 μA per channel.
All devices include a Power-On Reset (POR) feature.
This ensures the output is in a known state until the
minimum supply voltage has been reached before the
output responds to the inputs, thus preventing false
outputs during system power-up and power-down.
The TLV181x comparators have a push-pull output
stage capable of sinking and sourcing milliamps
of current when controlling an LED or driving a
capacitive load such as a MOSFET gate.
The TLV182x comparators have an open-drain output
stage that can be pulled up to 40 V independent of
comparator supply voltage.
