description
This device consists of four 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 so long as the difference
between the two supplies is 2 V to 28 V and V
voltage. Current drain is independent of the supply voltage. The outputs can be connected to other
open-collector outputs to achieve wired-AND relationships.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. There are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated in the recommended operating conditions section of this
specification 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 the network ground.
2. Differential voltages are at IN+ with respect to IN –.
3. Short circuits from the output to VCC can cause excessive heating and eventual destruction.
