3 Description

The TLV187x is a 40V high-speed comparator that

offers rail-to-rail inputs with a push-pull output-stage.

The TLV187x also has the ability to level shift via

separate input and output supplies. These features

coupled with 65ns propagation delay make this family

well-suited for bipolar zero-cross detection, Class D

audio amplifier systems or other applications where

level translation and propagation delay symmetry is

needed.

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

that 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 powerdown.

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.
