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 18µA 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 power-down.

These comparators also feature no output phase inversion with fault-tolerant inputs that can go up to 6V 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.
