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.
