DESCRIPTION
These devices consist of two independentprecisionvoltagecomparators,designedtooperatewith
single or dual supplies.
These differential comparators use the SGSTHOMSONsiliconlin MOSprocess givingtheman
excellent consumption-speedratio.
These devices are ideally suited for lowconsumption applications.

2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of the input and the output voltages must never exceed the magnitude of the positive supplyvoltage.
4. Short circuit from outputs to V
