SN65HVD1793D

Drivers, Receivers, Transceivers Overview

The SN65HVD1793D is a half-duplex RS-485 transceiver manufactured by Texas Instruments, designed for robust communication in noisy industrial environments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 115 kb/s. The device features integrated fault protection capable of withstanding voltages from -70 V to +70 V on the bus lines, ensuring protection against short circuits and electrostatic discharge. Packaged in an 8-pin SOIC (D) surface-mount format, it functions reliably across an extended temperature range of -40°C to +105°C. Key electrical characteristics include a typical operating supply current of 6 mA and propagation delays of 200 ns for both driver and receiver sections.

Drivers, Receivers, Transceivers Feature Summary

• Integrated high-voltage fault protection safeguards the transceiver against bus line shorts and extreme voltage conditions.
• Compliant with RS-485 standards for reliable half-duplex data transmission over balanced communication lines.
• Operates effectively in harsh electromagnetic environments due to built-in noise immunity and ESD protection capabilities.

Drivers, Receivers, Transceivers Applications

• Industrial automation systems requiring robust serial communication
• Building automation and control networks
• Process control instrumentation interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for SOIC-8 packages. Confirm RoHS compliance status through official manufacturer documentation before integration into regulated assemblies.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring standard RS-485 performance with enhanced fault tolerance. It is suitable for applications where moderate data speeds are sufficient but environmental ruggedness is critical. Compare power consumption requirements against higher-speed alternatives if energy efficiency is a primary constraint.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN65HVD179x series of RS-485 transceivers. It shares functional similarities with other members like the SN65HVD1794D but may differ in specific pin configurations or additional features such as shutdown modes.
