Overview

The devices in this series consist of dual comparators on a single monolithic substrate. The common-mode input voltage range includes ground even when the LM2903D 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 outputs to achieve wired-AND relationships.

The LM2903D is a dual-channel version available in the SOP8 and MSOP8 packages. All devices are specified for the temperature range from −40°C to +125°C.
