LMV7239 - 75 nsec, Ultra Low Pwr, Low Voltage, Rail-to-Rail Input Comparator w/ Open-Drain/Push-Pull Output

The LMV7235 and LMV7239 are ultra low power, low voltage, 75-ns comparators. They are ensured to operate over the full supply voltage range of 2.7 V to 5.5 V.These devices achieve a 75-ns propagation delay while consuming only 65 µA of supply current at 5V.

The LMV7235 and LMV7239 have a greater than rail-to-rail common-mode voltage range. Theinput common mode voltage range extends 200 mV below ground and 200 mV above supply, allowing bothground and supply sensing.

The LMV7235 features an open drain output. By connecting an externalresistor, the output of the comparator can be used as a level shifter.

The LMV7239features a push-pull output stage. This feature allows operation without the need of an externalpullup resistor.

The LMV7235 and LMV7239 are available in the 5-pin SC70 and 5-pin SOT-23 packages, whichare ideal for systems where small size and low power is critical.
