ISL3175EIBZ

Overview

The ISL3175EIBZ is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates on a single 3V to 3.6V supply and supports data rates up to 500kbps. The device features ±15kV IEC61000 ESD protection on the bus pins and incorporates full fail-safe receiver functionality. It utilizes a true 1/8 unit load design, enabling up to 256 devices on a network. The component is housed in an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated ±15kV IEC61000 ESD protection on RS-485 input/output pins
• Full fail-safe receiver design ensures logic high output when inputs are floating or shorted
• True 1/8 unit load architecture allows for extensive multi-drop networks without repeaters

Applications

• Remote utility meter reading systems requiring high node counts
• Industrial automation control networks
• Building automation and security systems

Procurement Notes

Verify the specific suffix 'IBZ' against official Renesas documentation to confirm RoHS compliance and lead-free status. Confirm that the package type matches the required PCB footprint. Ensure the operating voltage requirements align with the system's power supply specifications before procurement.

Selection Notes

Select this component for applications requiring robust ESD protection and low power consumption at 3.3V. The 500kbps speed is suitable for moderate baud rate industrial communication. Consider the 1/8 unit load capability if designing networks with more than 32 nodes. Verify thermal performance within the specified ambient temperature range.

Part Context

This part belongs to the ISL317xE series of low-power, high-speed RS-485/RS-422 transceivers from Renesas. The series shares common features such as fail-safe receivers and hot-plug capabilities. The ISL3175EIBZ specifically denotes the 500kbps slew-rate limited variant in an 8-pin SOIC package.

Replacement Considerations

Direct substitutes include other parts within the ISL317xE family, such as the ISL3172EIBZ or ISL3173EIBZ, provided their electrical characteristics like data rate and pinout compatibility match the design requirements.
