GENERAL DESCRIPTION

The TC1027 is a mixed-function device combining four general purpose, complimentary output comparators and a voltage reference in a single 16-pin package.

This increased integration allows the user to replace two packages, saving space, lowering supply current, and increasing system performance.

The TC1027 is designed specifically for operation from a single supply; however, operation from dual supplies is also possible. The power supply current drain is indepen dent of the magnitude of the power supply voltage. The TC1027 is optimized for low supply voltage and very low supply current operation (15µA max) making it ideal for battery operated applications.
