ISL3179EIBZ

Overview

The ISL3179EIBZ is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates on a single 3.3V supply and supports data rates up to 40 Mbps. The device features ±15kV IEC61000 ESD protection on the bus pins and full fail-safe receiver functionality. It utilizes a true 1/8 unit load, allowing up to 256 devices on the bus. The component is housed in a 14-lead SOIC package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• High-speed data transmission capability up to 40 Mbps for efficient communication.
• Robust electrostatic discharge protection rated at ±15kV IEC61000 on bus lines.
• Full fail-safe design ensures logic high output when inputs are floating or shorted.
• Low power consumption with minimal quiescent current draw.

Applications

• Industrial automation networks requiring robust node connectivity
• Building automation systems utilizing RS-485 protocols
• Meter reading infrastructure with high node density requirements

Procurement Notes

Verify the specific suffix 'IBZ' against official Renesas documentation to confirm the tape and reel packaging configuration. Ensure the order quantity aligns with standard manufacturing reel sizes. Confirm RoHS compliance status through the manufacturer's latest certification records prior to finalizing procurement.

Selection Notes

Select this component for designs requiring high-speed 40 Mbps performance over RS-485/RS-422 buses. It is suitable for environments demanding high ESD immunity without external protection components. Consider the 14-pin SOIC footprint for board space constraints compared to smaller packages.

Part Context

This part belongs to the ISL317xE family of low-power, high-speed transceivers. The series is designed to meet RS-485 and RS-422 standards while offering enhanced ESD protection. It serves as a critical interface component for serial communication in industrial and commercial applications.

Replacement Considerations

Direct substitutes include other members of the ISL317xE family such as ISL3172E or ISL3173E, provided the data rate and package compatibility match the design requirements. Verify pinout consistency before substitution.
