DESCRIPTION
These devices consist of four independentprecisionvoltagecomparators,designedtooperatewith
single or dual supplies.
These differential comparators use the SGSTHOMSONsilicon linMOSprocess givingtheman
excellent consumption-speedratio.
These devices are ideallysuited for lowconsumption applications.

Notes : 1. All voltage values, except differential voltage,are with respect tonetwork ground terminal.
2. Differential voltages are thenon-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of theinput and the output voltages must never exceed the magnitude of thepositive supply voltage.
