3 Description

The TLV183x and TLV184x are high-speed

comparators with operating voltages up to 40V. The

comparators offer rail-to-rail inputs with push-pull and

open-drain output options. These features coupled

with 65ns propagation delay make this family wellsuited

for high speed current sensing and voltage

protection applications.

All devices include a Power-On Reset (POR) feature

that makes sure the output is in a known state until

the minimum supply voltage has been reached. Once

this voltage has been reached, the output responds

to the inputs, thus preventing false outputs during

system power-up and power-down.

The TLV183x comparators have a push-pull output

stage, which are designed for applications where

symmetry between rising and falling output responses

is desired. The TLV184x comparators have an opendrain

output stage, making them appropriate for level

transition.
