3 Description

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.
