SN65HVD11QDR

Drivers, Receivers, Transceivers Overview

The SN65HVD11QDR is a half-duplex RS-485 transceiver manufactured by Texas Instruments, designed for balanced transmission lines. It operates with a single 3.3-V power supply and supports data rates up to 10 Mb/s. The device features one driver and one receiver within an SOIC-8 package. Electrical specifications include a minimum operating voltage of 3 V, a maximum of 3.6 V, and a typical operating supply current of 15.5 mA. It functions reliably across a temperature range from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Complies with ANSI TIA/EIA-485-A standards for multipoint bus communication
• Provides bus-pin ESD protection exceeding 16-kV human-body model ratings
• Includes short-circuit protection on differential outputs ranging from -7 V to 12 V
• Offers glitch-free power-up and power-down protection suitable for hot-plugging

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation networks
• Multipoint communication buses requiring high noise immunity

Drivers, Receivers, Transceivers Procurement Notes

Verify the Q suffix indicates automotive qualification status against the official datasheet. Confirm the DR suffix corresponds to the tape-and-reel packaging format. Ensure the component meets RoHS compliance requirements for the specific manufacturing date code. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and traceability.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 10-Mb/s data rate is required for RS-485 applications. Choose this part if the system design mandates operation at a 3.3-V supply voltage. Consider this transceiver for environments requiring extended temperature ranges up to 125°C. Verify that the SOIC-8 package dimensions fit the available PCB space constraints.

Drivers, Receivers, Transceivers Part Context

This device belongs to the SN65HVD11 series of high-speed RS-485 transceivers. It serves as a variant within the broader family of Texas Instruments interface ICs. The component shares functional similarities with other members of the HVD series but is distinguished by its specific 10-Mb/s signaling speed and automotive-grade qualification indicated by the Q prefix.
