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 rail-

to-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 makes sure 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.
