Description The LMV7251/LMV7255 are rail-to-rail input low voltage comparators, which can operate at supply voltage range of 1.8V to 5.0V.
The LMV7251/LMV7255 are available in space saving SC-70 or SOT23-5 packages. These comparators are ideal for low voltage and
space critical designs.
The LMV7251 features a push-pull output stage. This feature allows operation with minimum power consumption when driving a
load.
The LMV7255 features an open drain output. This allows the connection of an external resistor at the output. The output of
the comparator can be used as a level shifter.
The IC's are built with National Semiconductor's advance Submicron Silicon-Gate BiCMOS process. The LMV7251/LMV7255 have bipolar
inputs for improved noise performance and CMOS outputs for better rail-to-rail output performance.
