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.
