3 Description

The TLV323x 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.

Likewise, the TLV323x 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 are specified for operation across the

expanded temperature range of –40°C to 125°C.
