LM2903P-MAND

Overview

The LM2903P is a dual differential voltage comparator from Texas Instruments, designed for single-supply operation across a wide voltage range. It features an open-collector output configuration and includes ground in its common-mode input voltage range. The device operates within a supply voltage span of 2V to 36V (or ±1V to ±18V) and supports through-hole mounting in an 8-DIP package. It is compatible with TTL, CMOS, and MOS logic families.

Feature Summary

• Dual independent voltage comparators optimized for single-supply applications
• Open-collector outputs allowing wired-AND connections and logic compatibility
• Common-mode input voltage range extends to ground potential

Applications

• General-purpose voltage level detection
• Simple threshold switching circuits
• Power supply monitoring

Procurement Notes

Verify the exact suffix against official TI documentation, as 'M' is not standard for this series. Confirm the package type matches your PCB footprint requirements. Ensure the operating temperature range aligns with your system specifications before finalizing procurement.

Selection Notes

Select this component when low-cost, general-purpose comparison is required without high-speed demands. Consider the open-collector output limitations regarding pull-up resistor requirements. Evaluate if the propagation delay meets your circuit timing constraints compared to faster alternatives.

Part Context

This part belongs to the legacy LMx93/LM2903 family of dual comparators. It serves as a cost-effective alternative to operational amplifiers for non-linear switching applications. The DIP-8 package facilitates easy prototyping and through-hole assembly in industrial and consumer electronics.

Replacement Considerations

LM2903B or LM393B are direct next-generation replacements offering improved electrical characteristics. LM2903V is also a compatible variant within the same functional family.
