AM26LS31CDBRE4

Drivers, Receivers, Transceivers Overview

The AM26LS31CDBRE4 is a quad differential line driver manufactured by Texas Instruments, designed for RS-422 and RS-485 communication protocols. It operates within a supply voltage range of 4.75 V to 5.25 V, with a typical operating voltage of 5 V. The device supports data rates up to 10 Mb/s and draws a maximum operating supply current of 80 mA. It features four independent drivers in a single package. The component is housed in a 16-pin SOIC-Narrow surface-mount package and is rated for an extended industrial temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides four independent differential line drivers for balanced transmission lines
• Complies with TIA/EIA-422-B standards and ITU-T V.11 recommendations
• Designed for high-speed data transmission on long-distance serial buses

Drivers, Receivers, Transceivers Applications

• RS-422 multi-point communication systems
• RS-485 industrial network interfaces
• Balanced transmission line drivers for noisy environments

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's official datasheet to confirm RoHS compliance status and lead-free material composition. Confirm the package type matches the required PCB footprint, as variations exist between standard and narrow SOIC packages. Check for end-of-life notifications or discontinuation notices prior to finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad differential driver is required for RS-422 or RS-485 applications. Ensure the design accommodates the 80 mA supply current draw. Verify that the -40°C to +85°C temperature range meets the environmental requirements of the target application. Compare pinout compatibility if replacing older variants without the E4 suffix.

Drivers, Receivers, Transceivers Part Context

This part belongs to the AM26LS31 family of quad differential line drivers. It is functionally similar to the AM26LS31CD but includes the E4 suffix indicating specific manufacturing and compliance attributes. It serves as a core interface component for converting single-ended logic signals into differential signals for robust long-distance communication.

Drivers, Receivers, Transceivers Replacement Considerations

The AM26LS31CDRG4 is a documented alternative variant within the same family, offering reel packaging instead of tube. Other compatible parts include the AM26LS31CDE4 and AM26LS31CDR, though package and tape-and-reel specifications must be verified for direct substitution.
