SN65HVD1474DGK

Drivers, Receivers, Transceivers Overview

The SN65HVD1474DGK is a Texas Instruments RS-485 interface IC featuring a full-duplex transceiver in an 8-pin VSSOP package. It supports data rates up to 20 Mb/s with a supply voltage range of 3 V to 3.6 V and operates at 3.3 V. The device draws 1.1 mA of operating current and withstands ESD protection up to 16 kV per IEC standards. It functions within a temperature range of -40°C to +125°C, delivering differential outputs with driver currents of 60 mA and receiver currents of 8 mA. Power dissipation is rated at 255 mW, with propagation delays of 10 ns for the driver and 60 ns for the receiver.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DGK corresponds to the VSSOP-8 tube packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the procurement channel provides traceable origin records to guarantee component authenticity and quality assurance for critical industrial applications.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring full-duplex RS-485 connectivity without a shutdown pin. The VSSOP-8 package suits space-constrained PCB layouts compared to larger SOIC options. Verify that the system environment remains within the specified -40°C to +125°C operational limits. Ensure the bus topology does not exceed the electrical specifications for load capacitance and termination requirements defined in the technical data.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN65HVD147x series of high-speed RS-485 transceivers. It shares core electrical characteristics with variants like the SN65HVD1473DGS but differs in physical packaging. The DGK suffix specifically denotes the VSSOP-8 form factor, distinguishing it from tape-and-reel versions or other package types within the same functional family.

Drivers, Receivers, Transceivers Replacement Considerations

The SN65HVD1473DGS offers identical electrical performance in an MSOP-10 package. Designers must adjust footprint and pinout mapping if substituting between these package types. No direct pin-to-pin replacement exists for different package styles without schematic modification.
