LM397
Single General Purpose Voltage Comparator
General Description
The LM397 is a single voltage comparator with an input
common mode that includes ground. The LM397 is designed
to operate from a single 5V to 30V power supply or a split
power supply. Its low supply current is virtually independent
of the magnitude of the supply voltage.
The LM397 features an open collector output stage. This
allows the connection of an external resistor at the output.
The output can directly interface with TTL, CMOS and other
logic levels, by tying the resistor to different voltage levels
(level translator).
The LM397 is available in space saving SOT23-5 package
and pin compatible to TI’s TL331, single differential com-
parator.
