3 Description

The TLV321x and TLV322x 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 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 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.
