ISL3160EIBZ

Overview

The ISL3160EIBZ is a full-duplex RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates from a single +5V supply with a tolerance of 10%. The device supports data rates up to 40Mbps and features ±10kV IEC61000 ESD protection on RS-485 I/O pins, with >3kV HBM protection on other pins. It offers a large differential output voltage of 2.8V into 54Ω for enhanced noise immunity. The transceiver presents a 1/5 unit load, allowing up to 160 devices on the bus. It includes full fail-safe receiver functionality, hot-plug capability, and current limiting with thermal shutdown. Operating temperatures range from -40°C to +85°C for the IBZ package.

Feature Summary

• High ESD protection meeting IEC61000 standards on RS-485 I/O pins
• Full fail-safe receiver design ensuring logic high output during open or shorted conditions
• Hot-plug circuitry maintaining three-state outputs during power-up
• Low quiescent supply current with ultra-low shutdown mode

Applications

• Industrial automation networks requiring robust communication
• Building automation systems with multiple nodes
• Process control applications in harsh electrical environments

Procurement Notes

Verify the specific suffix 'IBZ' confirms the SOIC-8 package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through official Renesas documentation. Ensure the ordering part number matches the exact pinout and functional requirements for the target PCB layout.

Selection Notes

Select this component when a 5V supply is available and higher node density (up to 160 devices) is required compared to standard 1/32 unit load transceivers. Choose the ISL3160EIBZ over the ISL317xE series if 5V operation and 40Mbps speed are necessary rather than 3.3V operation. Consider the extended temperature variant (FBZ) if operation above +85°C is needed.

Part Context

The ISL3160E belongs to the Renesas RS-485/RS-422 interface IC family, originally developed under the Intersil brand. It is designed for balanced communication lines and complements lower-speed or lower-voltage variants like the ISL3158E and ISL3172E within the broader portfolio of serial interface solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult Renesas for direct replacements or evaluate compatible parts based on matching electrical specifications such as 5V supply, 40Mbps rate, and 1/5 unit load.
