3 Description

The TLV351x-Q1 is 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 7ns and a full supply

voltage range of 2.7V to 5.5V with a quiescent supply

current of only 1mA per channel.

All devices include a Power-On Reset (POR) feature.

This makes sure the output is in a known state (output

LOW) 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.

Likewise, the TLV351x-Q1 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 wellsuited

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.
