ISL3179EIRZ-T7A

Overview

The ISL3179EIRZ-T7A is a single RS-485 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 3.6 V, with a nominal operating voltage of 3.3 V. The device supports data transmission rates up to 40 Mb/s and functions reliably across an extended temperature range from -40 °C to +85 °C. Housed in a DFN-EP-10 surface-mount package, it integrates one driver and one receiver. The component complies with RoHS standards and exhibits moisture sensitivity.

Feature Summary

• High electrostatic discharge protection capabilities for robust signal integrity
• Full fail-safe receiver design ensuring logic high output during floating or undriven bus conditions
• Hot plug circuitry maintains high impedance state on outputs during power stabilization

Applications

• RS-485 industrial communication networks requiring high ESD immunity
• Half-duplex balanced data transmission systems
• Applications supporting up to 160 transceivers on a single bus without repeaters

Procurement Notes

Verify the specific ordering suffix T7A corresponds to the required reel packaging configuration. Confirm that the DFN-EP-10 package variant matches the target PCB footprint. Ensure the 3.3 V supply rail aligns with the specified minimum and maximum voltage limits before integration.

Selection Notes

Select this component for half-duplex applications requiring 40 Mb/s throughput. The low bus current characteristic allows significant network expansion beyond standard unit load limits. Verify thermal management requirements for the DFN-EP-10 package within the operational temperature range.

Part Context

This part belongs to the ISL3179E series of high ESD protected transceivers. It shares functional similarities with the ISL3180E but differs in duplex configuration. The series is designed for balanced communication interfaces meeting RS-485 and RS-422 standards.

Replacement Considerations

ISL3179EIUZ-T7A offers identical electrical specifications in a different package format.
