description
The LM339x2 consists of eight independent
voltage comparators that are designed to operate
from a single power supply over a wide range of
voltages. Operation from dual supplies is also
possible when the difference between the two
supplies is 2 V to 36 V and V
CC
is at least 1.5 V
more positive than the input common-mode
voltage. Current drain is independent of the
supply voltage. The outputs can be connected to
other open-collector outputs to achieve wire-AND
relationships.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these conditions beyond those indicated is not implied. Exposure to absolute-maximum-rated conditions for
extended periods may affect device reliability.
NOTES:
1. All voltage values, except differential voltages, are with respect to network GND.
2. Differential voltages are at IN + with respect to IN .
3. Short circuits from outputs to VCC can cause excessive heating and eventual destruction.
