The LMV7239-Q1 is a ultra low power, low voltage, 75-ns comparator. It is ensured to operate over the full supply voltage range of 2.7 V to 5.5 V. This device achieves a 75-ns propagation delay while consuming only 65 µA of supply current at 5 V.

The LMV7239-Q1 has a greater than rail-to-rail common-mode voltage range. The input common mode voltage range extends 200 mV below ground and 200 mV above supply, allowing both ground and supply sensing.

The LMV7239-Q1 features a push-pull output stage. This feature allows operation without the need of an external pullup resistor.

The LMV7239-Q1 is available in the 5-pin SC70 and 5-pin SOT-23 packages, which are ideal for systems where small size and low power is critical.
