HVD350BKRF-E

Overview

The HVD350BKRF-E is a high-speed, full-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates from a single 3.3 V supply and supports data rates up to 50 Mbps. The device features fail-safe circuitry that ensures a high logic state at the receiver output when inputs are open or disconnected. It includes thermal shutdown protection and ESD protection rated at ±15 kV according to IEC standards. The component is housed in an 8-pin SOIC package with a narrow body width of 3.90 mm.

Feature Summary

• Supports high-speed data transmission up to 50 Mbps
• Integrated fail-safe mechanism for reliable operation during input disconnection
• Robust electrostatic discharge protection compliant with IEC standards

Applications

• Industrial automation control systems
• Building automation networks
• Data communication equipment requiring RS-485 connectivity

Procurement Notes

Verify the specific ordering suffix BKRF against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements and interface standards before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component for applications requiring full-duplex RS-485 communication at speeds up to 50 Mbps. Consider the 3.3 V operating voltage and 8-pin SOIC package constraints. Evaluate thermal management needs given the integrated thermal shutdown feature. Confirm pinout compatibility with existing PCB layouts.

Part Context

This transceiver belongs to Renesas' high-speed RS-485 family designed for robust industrial communication. It complements other variants offering different speed grades or half-duplex configurations. The device addresses noise immunity and signal integrity challenges in multi-drop network environments typical of modern industrial settings.

Replacement Considerations

Check for direct substitutes such as the HVD350B series or compatible RS-485 transceivers from other manufacturers. Verify pin-to-pin compatibility and electrical parameter alignment. Ensure substitute parts meet the same ESD and fail-safe requirements.
