LMV7251/LMV7255
1.8V Low Voltage Comparator with Rail-to-Rail Input
General 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

process.
The
LMV7251/LMV7255 have bipolar inputs for improved noise
performance and CMOS outputs for better rail-to-rail output
performance.
