General Description

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

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.
