3 Description

The TLV321x-Q1 and TLV322x-Q1 are a family

of 5V single, dual and quad channel high-speed

comparators with push-pull or open-drain output

options. The family has an excellent speed-to-power

combination with a propagation delay of 40ns and

a full supply voltage range of 1.8V to 5V with a

quiescent supply current of only 40μA per channel.

These features, along with fast response time, railto-

rail inputs, low offset voltage and large output

drive current make the family well suited for current

sensing, zero-cross detection, and a variety of other

applications where speed is critical.

The family also includes a Power-on Reset (POR)

feature that holds the output in a known state until the

minimum supply voltage has been reached to prevent

output transients during system power-up and powerdown.

The TLV321x-Q1 have a push-pull output stage

capable of sinking and sourcing large currents for

symmetrical rise and fall times and quickly driving

capacitive loads such as MOSFET gates.

The TLV322x-Q1 have an open-drain output that can

be pulled-up below or beyond the supply voltage.

These devices are designed for low voltage logic

translators or combined OR'ed logic lines.

All devices are specified for operation across the

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