General Description

The TC1041 is a mixed-function device combining two

comparators and a voltage reference in a single 8-pin

package. The inverting inputs of both comparators 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

TC1041 operates from two 1.5V alkaline cells down to

which significantly extends battery life. The TC1041

provides a simple method for adding user-adjustable

hysteresis without feedback or complex external

circuitry. Hysteresis is adjusted with a simple resistor

divider on the HYST pin.

Rail-to-rail inputs and outputs allow operation from low

supply voltages with large input and output signal

swings.

Packaged in an 8-Pin SOIC or 8-Pin MSOP, the

TC1041 is ideal for applications requiring low power

and small packages.
