ISL3175EIUZ

Overview

The ISL3175EIUZ is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates on a single 3.3V supply with a voltage range of 3V to 3.6V. The device supports data rates up to 20Mbps and features ±15kV IEC61000 ESD protection on the bus pins. It incorporates full fail-safe receiver inputs, hot-plug capability, and true 1/8 unit load characteristics allowing up to 256 devices on the bus. The component is housed in an 8-pin MSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• IEC61000 ESD protection rated at ±15kV on RS-485 I/O pins
• Full fail-safe design ensuring logic high output for floating or shorted inputs
• Hot-plug circuitry maintaining three-state outputs during power-up
• Slew rate limited drivers to reduce electromagnetic interference

Applications

• Remote utility meter reading systems
• High node count field bus networks
• Security camera networks
• Building environmental control systems

Procurement Notes

Verify the specific suffix 'IUZ' corresponds to the MSOP-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected component matches the required 3.3V operating voltage specifications for the target application circuit.

Selection Notes

Select this component for applications requiring high noise immunity and robust ESD protection in industrial environments. The true 1/8 unit load feature enables extensive network topologies without repeaters. Verify that the slew rate limiting aligns with signal integrity requirements for long transmission lines.

Part Context

This part belongs to the ISL317xE series of low-power, high-speed RS-485/RS-422 transceivers. The series includes variants with different duplex configurations and package options. The ISL3175EIUZ specifically denotes the half-duplex version in the MSOP-8 package format.

Replacement Considerations

Direct substitutes within the same family include ISL3175EIBZ (SOIC-8 package). Other compatible variants are ISL3170E, ISL3171E, ISL3173E, ISL3174E, ISL3176E, and ISL3177E, depending on required duplex configuration.
