This device consists of four independentprecision voltage comparators. All these comparators were designedspecificallytooperatefromasinglepower supply over a wide range of voltages. Operation fromsplitpowersuppliesis also possible.

Thesecomparatorsalsohavea uniquecharacteristic in that the input common-modevoltagerange includesgroundeventhoughoperatedfromasingle powersupplyvoltage.

3. The dir ection of the input current is out of the IC due to t he P NP i nput stage. This current is essentially constant, independent of the state of t he output, so no loading charge exists on t he r eference of input lines.
