3 Description

The TLV187x is a 40V high-speed comparator family

that offers rail-to-rail inputs and a push-pull outputstage

with separate input and output supply pins.

These features coupled with 65ns propagation delay

make this family well-suited for bipolar zero-cross

detection, Class D audio amplifier systems, and other

applications where level translation and propagation

delay symmetry is needed.

This device includes a Power-On Reset (POR) feature

that holds the output 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 TLV187x has a push-pull output stage, making

them an excellent choice for applications where

symmetry between rising and falling output responses

is desired. This device offers the ability to level

translate for downstream devices at lower voltages

due to the separate input and output supplies.
