ISL3179EIBZ-T

Drivers, Receivers, Transceivers Overview

The ISL3179EIBZ-T is a half-duplex RS-485 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 incorporates full fail-safe receiver inputs that default to a logic high state when inputs are floating, shorted, or undriven. It utilizes an 8-lead narrow SOIC package and functions within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• High-speed communication capability supporting data rates up to 40 Mbps for efficient network throughput.
• Robust electrostatic discharge protection rated at ±15kV on RS-485 I/O pins per IEC61000 standards.
• Full fail-safe receiver design ensures a defined logic high output during open-circuit or undriven conditions.

Drivers, Receivers, Transceivers Applications

• Industrial automation networks requiring robust noise immunity and high-speed data transfer.
• Building automation systems utilizing RS-485 multi-drop configurations.
• Metering applications where high node counts and low quiescent current are beneficial.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the 'IBZ' designation corresponds to the lead-free RoHS-compliant variant in the narrow SOIC package. Cross-reference the manufacturer datasheet FN6365 for exact electrical characteristics and pinout definitions before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed RS-485 communication with integrated ESD protection. Ensure the system voltage aligns with the specified 3.3V operating range. Consider the 40 Mbps rate against cable length requirements to maintain signal integrity without additional equalization.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL317xE family of high ESD protected transceivers designed for balanced communication lines. It shares architectural similarities with the ISL3172E and ISL3173E but offers higher data rates suitable for demanding industrial environments.

Drivers, Receivers, Transceivers Replacement Considerations

The ISL3179EIUZ-T serves as a direct functional equivalent in the UQFN package. Verify thermal dissipation requirements and board space constraints when substituting between the SOIC and UQFN form factors.
