DS36277TMX

Overview

The DS36277TMX is a half-duplex RS-422/RS-485 transceiver manufactured by Texas Instruments. It integrates one driver and one receiver in an 8-pin SOIC package. The device supports data rates up to 20 Mb/s with a fixed operating supply voltage of 5 V. It operates within a temperature range of -40°C to +85°C and draws a typical quiescent current of 500 µA. The component lacks a shutdown function and is supplied in reel, cut tape, or MouseReel formats.

Feature Summary

• Supports multipoint communication on RS-485 buses
• Provides differential transmission for noise immunity
• Operates at high data speeds up to 20 Mb/s

Applications

• Industrial automation control systems
• Building automation networks
• Data acquisition systems

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and electrical characteristics match the design requirements. Ensure the ordering information aligns with the required packaging format such as reel or cut tape. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a single half-duplex transceiver is needed for RS-485 applications requiring 20 Mb/s performance. The fixed 5 V supply requirement limits use cases to compatible logic families. Verify that the SOIC-8 package fits the available PCB space and thermal constraints for the intended operating environment.

Part Context

This part belongs to the DS36277 series of interface ICs. It serves as a line transceiver for bidirectional data transfer. The TMX suffix indicates the tape and reel packaging variant. It is distinct from similar devices like the DS36276 which may offer different fail-safe features.

Replacement Considerations

Check for direct substitutes within the same family. Verify pin compatibility and electrical parameters against alternative part numbers before substitution.
