The device consists of four independent voltage comparators designed specifically to operate from a single power supply and, typically, to draw 60-µA drain current over a wide range of voltages. Operation from split power supplies also is possible, and the ultra-low power-supply drain current is independent of the power-supply voltage. Applications include limit comparators, simple analog-to-digital converters, pulse generators, square-wave generators, time-d...
