The TLV4H290-SEP and TLV4H390-SEP are quad channel comparators which offer low input offset voltage and an excellent speed-to-power combination with a propagation delay of 100ns. Operating voltage range of 1.65V to 5.5V with a quiescent supply current of 25μA per channel.

This device family includes fault tolerant inputs that allow voltage to be applied to the input pins even when there is no power supply applied to the comparator making them well-suited for applications where power supply sequencing is a challenge. Likewise, these comparators feature no output phase inversion with fault-tolerant inputs that can go up to 6V without damage.

The TLV4H290-SEP comparator has an open-drain output stage that can be pulled below or beyond the supply voltage, making the output appropriate for level translation. The TLV4H390-SEP comparator has a push-pull output stage capable of both sinking and sourcing current.

The TLV4H290-SEP and TLV4H390-SEP are available in a plastic 14-pin SOT-23 package with radiation tolerance up to 43MeV·cm² /mg.
