3 Description
The TLV902x and TLV903x are a family of dual and
quad channel comparators. The family offers low input
offset voltage, integrated Power-On Reset (POR)
circuitry, and fault-tolerant inputs with an excellent
speed-to-power combination with a propagation delay
of 100 ns. Operating voltage range of 1.65 V to 5.5 V
with a quiescent supply current of 18 μA per channel.
This device family also includes a Power-on Reset
(POR) feature that ensures the output is in a known
state until the minimum supply voltage has been
reached and a small time period passed before the
output starts responding to the inputs. This prevents
output transients during system power-up and powerdown.
These comparators also feature no output phase
inversion with fault-tolerant inputs that can go up
to 6-V without damage. This makes this family
of comparators well suited for precision voltage
monitoring in harsh, noisy environments.
The TLV902x comparators have an open-drain output
stage that can be pulled below or beyond the supply
voltage, making it appropriate for low voltage logic
and level translators.
The TLV903x comparators have a push-pull output
stage capable of sinking and sourcing milliamps
of current when controlling an LED or driving a
capacitive load such as a MOSFET gate.
The TLV902x and TLV903x are specified for the
Industrial temperature range of -40°C to +125°C
and are available in a standard leaded and leadless
packages.
