ISL32173EFBZ-T

Overview

The ISL32173EFBZ-T is an RS-422/RS-485 interface integrated circuit manufactured by Renesas Electronics Corporation. It functions as a quad receiver with zero drivers, designed for high-speed data communication. The device supports data rates up to 80 Mbps and operates within a supply voltage range of 3.0 V to 5.5 V. Key electrical specifications include a maximum operating current of 800 µA and robust electrostatic discharge (ESD) protection rated at ±15 kV. The component is housed in a 16-lead SOIC-Narrow package suitable for surface mount technology. It is engineered for reliable performance across an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• Quad receiver architecture providing four independent signal inputs for differential bus applications
• High-speed data transmission capability supporting baud rates up to 80 Mbps
• Integrated ±15 kV ESD protection on all pins to safeguard against electrostatic discharge events
• Low power consumption design with reduced quiescent current for energy-efficient operation

Applications

• Industrial control systems requiring robust serial communication interfaces
• Building automation networks utilizing RS-485 multi-drop configurations
• Data acquisition systems interfacing with remote sensors and field devices

Procurement Notes

Verify the specific suffix BZ-T against official Renesas documentation to confirm packaging format and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for end-of-life notices or discontinuation announcements as availability may be limited. Ensure compatibility with existing PCB footprint requirements for the 16-SOIC package.

Selection Notes

Select this component when a dedicated quad receiver is required for RS-422 or RS-485 buses without integrated driver functionality. Consider the 80 Mbps speed limit and ±15 kV ESD rating for harsh industrial environments. Evaluate the 3.0 V to 5.5 V supply range against system power constraints. Compare thermal performance and package size against alternative receivers if space is limited.

Part Context

This part belongs to the ISL3217xE family of high-speed transceivers from Renesas Intersil. It complements other variants like the ISL32172E which includes drivers. The series is designed for demanding communication protocols where noise immunity and speed are critical. It serves as a building block for complex serial communication networks in industrial and commercial equipment.

Replacement Considerations

Check for direct pin-compatible substitutes within the ISL3217x series such as the ISL32173EFVZ. Verify functional equivalence regarding data rate, voltage range, and ESD protection levels before substitution.
