3 Description

The TLV902x and TLV903x are a family of dual and

quad channel comparators. The family offers low input

offset voltage, fault-tolerant inputs and a excellent

speed-to-power combination with a propagation delay

of 100 ns with a quiescent supply current of only 18

μA per channel.

The 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 to

prevent output transients during system power-up and

power-down.

These comparators also feature fault-tolerant inputs

that can go up to 6-V without damage with no

output phase inversion. This makes this family

of comparators designed for precision voltage

monitoring in harsh, noisy environments.

The TLV902x have an open-drain output that may be

pulled-up below or beyond the supply voltage, making

it appropriate for low voltage logic translators.

The TLV903x have a push-pull output stage capable

of sinking and sourcing many milliamps of current to

drive LEDs or a capacitive load such as a MOSFET

gate.

The TLV90x0 and TLV90x1 are alternate pinouts of

the single device.

The family is specified for the Industrial temperature

range of -40°C to +125°C and are available in a

standard leaded and leadless packages.
