Overview
The LM2903ITLX/NOPB is a dual differential voltage comparator manufactured by Texas Instruments. It operates on a single power supply ranging from 2 V to 36 V, with a typical quiescent current of 1 mA per channel. The device features an open-collector output configuration compatible with CMOS and TTL logic families. It provides a typical response time of 1.3 μs and supports an input common-mode voltage range that includes ground. The component is designed for operation within a temperature range of -40°C to +125°C and is housed in an 8-pin HTSSOP package.
Feature Summary
- Dual differential voltage comparison capability
- Open-collector output structure for logic compatibility
- Wide single-supply voltage operation range
- Extended industrial temperature performance
Applications
- General-purpose analog signal comparison
- Voltage monitoring circuits
- Logic interface level shifting
- Over-voltage detection systems
Procurement Notes
Verify the specific suffix 'ITLX' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging specifications and temperature grade. Ensure the ordering part number matches the required HTSSOP-8 variant. Cross-reference the datasheet revision date to validate electrical characteristics before final procurement decisions.
Selection Notes
Select this component when a dual comparator with wide supply voltage tolerance is required. The open-collector output allows flexible interfacing with various logic levels. Consider the thermal management requirements associated with the HTSSOP package for high-density applications. Verify that the 1.3 μs response time meets the system's switching speed requirements.
Part Context
This device belongs to the LMx93/LM2903 family of dual comparators from Texas Instruments. These components are engineered for low-power applications requiring reliable voltage threshold detection. The family shares core architectural similarities but varies in packaging and specific electrical parameters based on the suffix designations.
Replacement Considerations
LM2903DR: SOIC-8 package variant with similar electrical characteristics. LM2903MX/NOPB: SOIC-8 package alternative. LM2903IDR: Industrial temperature grade SOIC-8 version.
