3 Description

The TLV183x-Q1 and TLV184x-Q1 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-Q1 comparators have a push-pull

output stage, which are designed for applications

where symmetry between rising and falling output

responses is desired. The TLV184x-Q1 comparators

have an open-drain output stage, making them

appropriate for level transition.
