HVC357TRF-E

Overview

The HVC357TRF-E is a high-voltage level translator manufactured by Renesas Electronics Corporation. It provides bidirectional voltage translation between low-voltage logic domains and high-voltage buses, supporting supply voltages up to 40V on the high-voltage side while operating from a low-voltage supply as low as 1.65V. The device features three independent channels, enabling simultaneous translation for multiple data lines. It incorporates internal pull-up resistors and offers robust ESD protection rated at ±8kV Human Body Model (HBM) and ±1kV Charged Device Model (CDM). Designed for applications requiring isolation or level shifting in mixed-voltage systems, it ensures signal integrity across varying power domains.

Feature Summary

• Bidirectional voltage translation capability between low-voltage and high-voltage logic domains
• Three independent channels for multi-line data translation
• Integrated ESD protection meeting stringent industrial standards
• Internal pull-up resistors simplify external circuit design

Applications

• Industrial automation systems with mixed voltage sensors
• Automotive infotainment and body control modules
• High-voltage I/O interfaces in consumer electronics
• Level shifting for communication buses like I2C or SPI in harsh environments

Procurement Notes

Verify the specific suffix 'TRF-E' against official Renesas documentation to confirm tape-and-reel packaging and environmental compliance status. Ensure the ordering part number matches the exact package type and temperature range required for your design. Cross-reference with authorized distributors to confirm current availability and lead times, as component stock levels fluctuate. Always request the latest datasheet revision to ensure compatibility with your system requirements.

Selection Notes

Select the HVC357TRF-E when designing systems that require translating signals between 1.65V logic and buses operating up to 40V. Consider its three-channel architecture if multiple parallel data lines need translation simultaneously. Evaluate the internal pull-up resistor values against your bus capacitance and speed requirements. Verify that the ESD protection ratings meet the safety standards of your target application environment, particularly for automotive or industrial settings.

Part Context

This component belongs to Renesas' high-voltage level translator family, designed to bridge gaps between modern low-power digital circuits and legacy or high-voltage analog/digital interfaces. Unlike standard 3.3V-to-5V translators, this series supports significantly higher voltage differentials, making it suitable for specialized industrial and automotive applications where standard logic families cannot interface directly with high-side components or sensors.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided reference material. Engineers should consult Renesas' official cross-reference tools or contact technical support directly for validated alternatives. When evaluating potential replacements, ensure that the substitute device matches the channel count, maximum voltage ratings, and package dimensions to maintain PCB layout compatibility.
