DESCRIPTION

These devices consist of two independent preci- sion voltagecomparators,designedto operate with single or dual supplies. These differential comparators use the SGS- THOMSON silicon lin MOS process giving them an excellent consumption-speed ratio. These devices are ideally suited for low consump- tion applications.

All voltage values, except differential voltage, are with respect to network ground terminal. 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 supply voltage. 4. Short circuit from outputs to VCC + can cause excessive heatingand eventual destruction.
