DESCRIPTION
These devices consist of four independent preci-
sion voltage comparators, 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.
Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
The magnitude of the input and
+
output voltages must never exceed the magnitude of the positive supply voltage.

Short circuit from outputs to V
