ISL3179EFBZ

Overview

The ISL3179EFBZ is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It operates on a single 3.3V supply and supports data rates up to 40Mbps. The device features high ESD protection, full fail-safe receivers, and hot-plug capability. It utilizes an SOIC-8 package and functions within a temperature range of -40°C to +125°C. The quiescent supply current is typically 4mA.

Feature Summary

• High electrostatic discharge (ESD) protection on RS-485 I/O pins
• Full fail-safe receiver design for undriven bus conditions
• Hot-plug circuitry maintains high impedance during power-up

Applications

• Industrial automation networks
• Building automation systems
• Utility meter reading systems

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements and interface standards before procurement.

Selection Notes

Select this component for applications requiring robust ESD protection and operation at elevated temperatures. Verify that the 3.3V supply voltage aligns with the target system architecture and that the SOIC-8 package fits the PCB layout constraints.

Part Context

This part belongs to the ISL3179E series of high-speed, low-power transceivers designed for balanced communication networks. It complements other variants in the family that may offer different packaging options or extended temperature ranges.

Replacement Considerations

Check for direct pin-compatible alternatives within the ISL317xE series. Verify electrical parameters such as data rate and ESD ratings when considering substitutes from other manufacturers.
