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