Overview
The LM2903MX/E7002290 is a dual differential voltage comparator manufactured by Texas Instruments. It belongs to the LM193/LM293/LM393/LM2903 family of low power, low offset voltage devices designed for single-supply operation over a wide voltage range. The component features an open-collector output configuration and includes ground in its common-mode input voltage range. This specific part number indicates an end-of-life status, with discontinuance notifications issued by the manufacturer.
Feature Summary
- Dual differential voltage comparison capability
- Low power consumption design
- Low offset voltage specification
- Open-collector output structure
Applications
- Single-supply voltage monitoring
- Threshold detection circuits
- Simple logic interface conversion
Procurement Notes
This component is officially classified as End-of-Life (EOL) by Texas Instruments. Discontinuance notifications have been published, indicating that the manufacturer will cease production. Procurement should focus on verifying final time buy availability or identifying qualified replacement components from current active product lines to ensure long-term supply chain stability.
Selection Notes
Designers requiring this functionality should evaluate alternative parts within the LMx93 series that remain in active production. Selection criteria must account for pin compatibility and electrical parameter equivalence, specifically focusing on offset voltage and propagation delay characteristics suitable for the intended application environment.
Part Context
The LM2903MX/E7002290 is part of the broader LM2903 family, which shares architectural similarities with the LM193, LM293, and LM393 comparators. These devices are characterized by their ability to operate from a wide range of single supply voltages while maintaining low power dissipation. The MX suffix typically denotes a tape and reel packaging format.
Replacement Considerations
Verify active equivalents such as LM2903DR or LM2903IDR from Texas Instruments. Ensure that any substitute maintains the dual comparator topology and open-collector output requirements of the original design.
