3 Description

The TLV323x-Q1 are 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 20ns and a full supply voltage range of 2.7V to 5V with a quiescent supply current of only 200μA per channel.

All devices include a Power-On Reset (POR) feature. Until the minimum supply voltage has been reached and the output responds to the inputs, POR places the output is in a known state, thus preventing false outputs during system power-up and power down.

The TLV323x-Q1 comparators have a push-pull output stage capable of sinking and sourcing milliamps of current when controlling an LED or driving a capacitive load such as a MOSFET gate.
