ISL3160EIBZ-T7A

Overview

The ISL3160EIBZ-T7A is a full-duplex RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates on a single +5V supply and supports data rates up to 40 Mbps. The device features ±10kV IEC61000 ESD protection on RS-485 I/O pins and >3kV Class 3 HBM on other pins. It offers a large differential output voltage of 2.8V into 54Ω, ensuring high noise immunity. The unit load is 1/5, allowing up to 160 devices on the bus. Operating temperature ranges from -40°C to +85°C for the IBZ suffix. Key electrical parameters include 11ns maximum Tx propagation delay, 1μA shutdown current, and a common-mode input range of -7V to +12V.

Feature Summary

• High electrostatic discharge (ESD) protection compliant with IEC61000 standards on RS-485 I/O pins.
• Low unit load design enabling connection of up to 160 transceivers on a single bus without repeaters.
• Hot-plug capability ensures transmitter and receiver outputs remain in three-state during power-up.
• Integrated current limiting and thermal shutdown mechanisms protect against driver overload conditions.

Applications

• Industrial automation networks requiring robust communication over long distances.
• Building automation systems utilizing RS-485 or RS-422 protocols.
• Isolated applications driving opto-couplers due to high receiver input low-level voltage.

Procurement Notes

Verify the specific suffix 'IBZ' confirms the industrial temperature range (-40°C to +85°C). Confirm the package type matches SOIC-8 narrow. Check RoHS compliance status as indicated in official documentation. Ensure the ordering quantity aligns with factory reel specifications. Validate that the component source is an authorized distributor to guarantee authenticity.

Selection Notes

Select this component when high ESD immunity is critical for RS-485 interfaces. Choose the ISL3160E for full-duplex applications requiring up to 40 Mbps data rates. Consider the 1/5 unit load feature for dense network topologies supporting many nodes. Verify that the +5V supply voltage matches the system power architecture. Ensure the operating temperature range meets the environmental requirements of the deployment site.

Part Context

This part belongs to the ISL3160E series of ruggedized interface transceivers. It is designed for harsh environments where signal integrity and device protection are paramount. The series emphasizes high noise immunity through large differential output voltages. It serves as a reliable solution for balanced communication lines in industrial settings.

Replacement Considerations

Direct substitutes within the same family may include variants with different temperature ratings or packaging options. Cross-referencing pinouts and electrical characteristics is essential before substitution. Verify compatibility with existing bus loading calculations if replacing multiple units.
