TI TLV1812DR

The TLV181x and TLV182x are a family of 40 Volt single, dual and quad channel comparators with multiple output options. The family offers rail-to-rail inputs with push-pull or open-drain output options. The family has an excellent speed-to-power combination with a propagation delay of 420 ns with a full supply voltage range of 2.4 V to 40 V with a quiescent supply current of only 5 μA per channel. All devices include a Power-On Reset (POR) feature. This ensures 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 power-down. The TLV181x 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. The TLV182x comparators have an open-drain output stage that can be pulled up to 40 V independent of comparator supply voltage.
