LMV7239 Datasheet | National Semiconductor

Description The LMV7235/39 are ultra low power, low voltage, 45ns parators. They are guaranteed to operate over the full supply voltage range of 2.7V to 5V. These devices achieve a 45ns propagation delay while consuming only 65µA of supply current at 5V. The LMV7235/39 have a greater than rail-to-rail mon mode voltage range. The input mon mode voltage range extends 200m V below ground and 200m V above supply, allowing both ground and supply sensing. The LMV7235 features an open drain output. By connecting an external resistor, the output of the parator can be used as a level shifter. The LMV7239 features a push-pull output stage. This feature allows operation without the need of an external pull-up resistor. The LMV7235/39 are available in the SC70-5 and SOT23-5 packages, which are ideal for systems where small size and low power is critical.
