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 well-suited 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.
