extended periods may affect device reliability.

The TC1040 is a mixed-function device combining two comparators and a voltage reference in a single 8-pin package. The inverting input of Comparator A and the non-inverting input of Comparator B are internally connected to the
reference.

This increased integration allows the user to replace two packages, which saves space, lowers supply current and increases system performance. The TC1040 operates from two 1.5V alkaline cells down to VDD = 1.8V. It requires only 10µA typical of supply current, which significantly extends battery life. A low power shutdown input (SHDN) disables one of the comparators, placing its outputs in a high-impedance state. This mode saves battery power and allows
comparator outputs to share common analog lines (multiplexing). Shutdown current is 6µA (typical).

Rail-to-rail inputs and outputs allow operation from low supply voltages with large input and output signal swings.

Packaged in an 8-Pin MSOP, the TC1040 is ideal for applications requiring low power level detection.
