STMicroelectronics LM2903W Low-Power Dual Voltage Comparator Datasheet
This document is a preliminary datasheet for the LM2903W, a low-power dual voltage comparator designed to operate from a single supply over a wide voltage range or split power supplies. The device consists of two independent comparators with input common-mode voltage ranges that include the negative rail, even when operating from a single supply.
Key features include very low supply current independent of the supply voltage, low input bias and offset currents, and low output saturation voltage. The outputs are compatible with TTL, DTL, ECL, MOS, and CMOS logic families. All pins are protected against electrostatic discharge up to 2 kV.
