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.
