SN65HVD33RHLR

Drivers, Receivers, Transceivers Overview

The SN65HVD33RHLR is a full-duplex RS-422 and RS-485 transceiver manufactured by Texas Instruments. It integrates one driver and one receiver within a single package, supporting data rates up to 23 Mbps. The device operates on a supply voltage range of 3 V to 3.6 V, with a typical operating current of 800 µA. It features a 14-pin SOIC package and functions reliably across an extended temperature range from -40°C to +85°C. Key electrical characteristics include a receiver hysteresis of 50 mV and compliance with industry-standard communication protocols.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix RHLR against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles defined in the manufacturer's datasheet before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring full-duplex RS-422 or RS-485 connectivity at speeds up to 23 Mbps. It is appropriate for applications needing low standby current and operation within standard industrial temperature ranges. Compare pinout and electrical parameters against alternative transceivers if system constraints differ.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN65HVD3x series of high-speed RS-485/RS-422 transceivers from Texas Instruments. The series is designed for robust communication in noisy industrial environments. The SN65HVD33 variant specifically offers full-duplex capability, distinguishing it from half-duplex models within the same family.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct substitutes such as the SN65HVD33DR or SN65HVD33PW depending on required packaging (reel vs. tube). Verify that any replacement maintains identical pin configurations and electrical ratings to ensure seamless integration without redesign.
