THVD1410DGK

Drivers, Receivers, Transceivers Overview

The THVD1410DGK is a half-duplex RS-485 transceiver manufactured by Texas Instruments, designed for industrial communication applications. It operates within a supply voltage range of 3.3 V to 5 V and supports data rates up to 20 Mbps. The device incorporates ±18-kV IEC ESD protection on the bus pins, ensuring robustness in harsh environments. It features fail-safe circuitry that guarantees a high logic state when the differential input is open or below a specific threshold. The component is housed in an 8-pin VSSOP package with a thermal pad, suitable for surface-mount assembly.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±18-kV IEC ESD protection on A and B bus terminals
• Fail-safe receiver design ensures defined output states during idle conditions
• Low-power shutdown mode minimizes current consumption during non-active periods

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation and security networks
• Factory floor sensor interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the DGK suffix to confirm the VSSOP-8 package type and tape-and-reel quantity. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status through the official datasheet before procurement. Cross-reference the manufacturer's latest documentation for any pinout revisions or recommended operating conditions.

Drivers, Receivers, Transceivers Selection Notes

Select this component when RS-485 communication requires high ESD immunity without external protection diodes. The 20 Mbps rate suits moderate-speed data transmission needs. Consider the VSSOP package constraints for thermal dissipation if multiple units operate simultaneously. Verify that the 3.3-V to 5-V supply range matches the system power architecture.

Drivers, Receivers, Transceivers Part Context

This device belongs to the THVD1410 series of RS-485 transceivers from Texas Instruments. The series focuses on providing integrated ESD protection to simplify board design and reduce component count. These transceivers are engineered for reliable operation in electrically noisy industrial environments where signal integrity is critical.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other TI RS-485 transceivers with similar ESD ratings and package types, such as the SN65HVD1785 or THVD1400, provided pinouts and electrical characteristics align with the existing design constraints.
