LM2903DQ

36-V Dual Comparators

Overview

The LM2903DQ consists of dual comparators on a single monolithic substrate. The common-mode input voltage range includes ground even when the LM2903DQ is operated from a single supply. The low power supply current drain makes these comparators suitable for battery operation. These types are designed to directly interface with TTL and CMOS. The current drain is independent of the supply voltage. The outputs can be connected to other open-collector or open-drain outputs to achieve wired-AND relationships.

The LM2903DQ is a dual-channel version available in an 8-pin SOP package. The LM2903DQ is specified for the temperature range from −40°C to +125°C.
