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 ORed logic lines.
All devices are specified for operation across the
expanded temperature range of –40°C to 125°C.
