ISL3171EIBZ-T7A

Overview

The ISL3171EIBZ-T7A is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates on a single 3.3V supply and supports data rates up to 250 kbps. The device features ±15kV IEC61000 ESD protection, full fail-safe receivers, and true 1/8 unit load capability for up to 256 nodes. It utilizes an SOIC-8 surface-mount package with an operating temperature range of -40°C to +85°C.

Feature Summary

• IEC61000 ESD protection on RS-485 I/O pins
• Full fail-safe receiver design
• True 1/8 unit load bus loading

Applications

• Remote utility meter reading systems
• Industrial automation networks
• Building control systems

Procurement Notes

Verify the specific suffix 'T7A' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the SOIC-8 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring low-speed, robust communication over long distances. The 250 kbps rate suits simple command structures. Verify that the 3.3V logic levels align with the host microcontroller interface. Consider the thermal shutdown feature for environments with potential driver overload conditions.

Part Context

This part belongs to the ISL317xE series of low-power, high-speed RS-485/RS-422 transceivers. It shares core architectural features with siblings like the ISL3172E and ISL3175E, differing primarily in specified data rate capabilities and slew rate limitations defined by the specific model variant within the family.

Replacement Considerations

Direct substitutes include ISL3172EIBZ-T7A and ISL3175EIBZ-T7A from the same manufacturer. These alternatives offer higher data rates but maintain pin compatibility and similar electrical characteristics. Verify functional equivalence regarding ESD protection levels and unit load specifications.
