ISL32175EIVZ

Overview

The ISL32175EIVZ is a low-power RS-485 transceiver manufactured by Renesas Electronics Corporation. It supports data rates up to 250 kbps and operates from a single 3V to 5.5V supply. The device features one driver and one receiver, with ESD protection rated at ±15kV (HBM) on RS-485 bus pins. It includes fail-safe circuitry to ensure the receiver output defaults to a high state when the differential input is open. The unit is housed in an 8-TSSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated fail-safe mechanism guarantees a high logic level for the receiver output during idle or disconnected bus conditions.
• Provides robust electrostatic discharge protection on all bus terminals, ensuring reliability in electrically noisy environments.
• Supports half-duplex communication with independent driver enable and receiver enable control pins.

Applications

• Industrial automation systems requiring reliable serial communication
• Building automation and control networks
• Metering infrastructure utilizing RS-485 protocols

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout compatibility and thermal specifications. Confirm RoHS compliance status and moisture sensitivity level prior to integration into surface-mount assembly processes. Ensure the ordering part number matches the exact package variant required for the design.

Selection Notes

Select this component for applications requiring moderate data speeds with low power consumption. It is suitable for designs needing integrated ESD protection without external components. Verify that the operating voltage range aligns with the system's available power rails and that the thermal performance meets the enclosure requirements.

Part Context

This device belongs to the ISL3217xE family of RS-485 transceivers designed for industrial and commercial serial communication interfaces. The family offers various configurations including full-duplex and multi-drop capabilities. This specific model provides a cost-effective solution for basic half-duplex networking needs within the broader Renesas interface portfolio.

Replacement Considerations

Consult official substitution guides for compatible alternatives such as the MAX3217E series or similar RS-485 transceivers with matching pinouts and electrical characteristics. Verify functional equivalence regarding drive strength and ESD ratings before implementation.
