DS26LS31ME-SMD

Overview

The DS26LS31ME-SMD is a quad high-speed differential line driver manufactured by Texas Instruments, designed for digital data transmission over balanced lines. It complies with EIA Standard RS-422 and Federal Standard 1020 requirements. The device provides unipolar differential drive to twisted-pair or parallel-wire transmission lines. It features TRI-STATE outputs and a common enable/disable function for all four drivers. The component operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating voltage of 5 V. It supports data rates up to 10 Mb/s and functions across an extended temperature range from -55°C to +125°C.

Feature Summary

• Quad differential line driver architecture supporting RS-422 standards
• TRI-STATE output capability for bus line sharing
• Common enable and disable control for all drivers
• Extended industrial temperature operation range

Applications

• Digital data transmission over balanced twisted-pair lines
• Parallel-wire transmission line interfaces
• RS-422 compliant communication systems

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm package type and material composition. Ensure compatibility with existing board layouts and thermal management requirements. Confirm availability status as some variants may have limited supply or obsolescence notices. Validate RoHS compliance and lead-free status if required by assembly specifications.

Selection Notes

Select this component when a quad differential driver is needed for RS-422 applications requiring high-speed data transfer. Consider the SMD package variant for surface mount assembly processes. Evaluate power consumption and thermal dissipation capabilities relative to the system's ambient conditions. Compare pinout compatibility with alternative quad drivers if space constraints exist.

Part Context

This part belongs to the DS26LS31 family of quad differential line drivers. It shares functional similarities with other members like the DS26LS31N and DS26LS31MW but differs in packaging and potentially qualification levels. The series is designed for robust noise immunity in noisy industrial environments.

Replacement Considerations

Publicly confirmed substitutes include the AM26LS31 series for similar functionality. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
