Microchip Technology TC1040
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.| Part No. | TC1040 |

GENERAL DESCRIPTION
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.
