DESCRIPTION
The LM7221 is a micropower CMOS comparator
available in the space saving 5-Pin SOT-23 package.
This makes this comparator ideal for space and
weight critical designs. The LMC7221 is also
available in the 8-Pin SOIC package. The LMC7221
is supplied in two offset voltage grades, 5 mV and 15
mV.
The open drain output can be pulled up with a
resistor to a voltage which can be higher or lower
than the supply voltage—this makes the part useful
for mixed voltage systems.
For a tiny comparator with a push-pull output, please
see the LMC7211 datasheet.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
