Non-inverting Input 4
These devices consist of four independent preci-
sion voltagecomparators,designedto operatewith
single or dual supplies.
These differential comparators use the SGS-
THOMSON silicon lin MOS process giving them an
excellent consumption-speed ratio.

Notes : 1. All voltage values, except differential voltage, are with respect to network ground terminal.
2. Differential voltages are thenon-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 heating and eventual destruction.

to 4V with RL = 100kΩ to VCC
2. Maximum values including unavoidable inaccuracies of the industrial test.
3. The response time which is specified is the internal between the input signal and the instant when the output signal crosses 1.4V.
