THVD1552DR

Drivers, Receivers, Transceivers Overview

The THVD1552DR is a full-duplex RS-485 transceiver manufactured by Texas Instruments, designed for high-speed data 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 50 Mb/s. The device features one driver and one receiver housed in a 14-SOIC package. Key electrical specifications include a quiescent current of 700 uA, an output current capability of 60 mA, and power dissipation of 350 mW. It provides robust ESD protection rated at +/-18 kV according to IEC standards. The component functions reliably across an extended temperature range from -40°C to +125°C.

• Building automation networks utilizing RS-485 protocols
• Factory floor equipment interfacing in electrically noisy environments

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DR' indicates reel packaging when sourcing components. Confirm RoHS compliance status matches current manufacturing standards. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check for any recent product change notices regarding assembly sites or material composition updates before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex RS-485 connectivity without shutdown functionality. Compare against half-duplex alternatives like the THVD1550 if bidirectional single-wire communication suffices. Consider the 14-pin SOIC footprint constraints during PCB layout planning. Evaluate the 50 Mb/s speed requirement against lower-speed legacy interfaces to ensure optimal performance matching.

Drivers, Receivers, Transceivers Part Context

This part belongs to the THVD15xx series of 5 V RS-485 transceivers from Texas Instruments. It complements other variants such as the THVD1552D (tube packaging) and THVD1550 (half-duplex). The series focuses on providing robust interface solutions for industrial applications with enhanced protection features.

Drivers, Receivers, Transceivers Replacement Considerations

The THVD1552D serves as a direct functional equivalent differing only in packaging format. Verify pin compatibility and electrical parameters match exactly when substituting.
