3 Description

The TLV351x-Q1 is a family of 5V single and dual channel comparators with push-pull outputs. The family has an excellent speed-to-power combination with a propagation delay of 6ns and a full supply voltage range of 2.7V to 5.5V with a quiescent supply current of only 1mA per channel.

All devices include a Power-On Reset (POR) feature. This makes sure the output is in a known state (output LOW) 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.

Likewise, the TLV351x-Q1 are conveniently available in standard leaded and leadless packages with features such as rail-to-rail inputs, low offset voltage, and large output drive current. These features along with fast response time make the comparators well-suited for current sensing, zero-cross detection, and a variety of other applications where precision and speed is critical.

All devices operate across the expanded temperature range of –40°C to 125°C.
