ISL31475EIBZ-T7A

Overview

The ISL31475EIBZ-T7A is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 1 Mb/s. The device features overvoltage protection (OVP) rated at 40V on the bus pins and an extended common-mode rejection range of ±15V. It functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in an 8-lead SOIC, this component integrates one driver and one receiver for robust differential communication.

Feature Summary

• Provides fault protection with 40V overvoltage capability on the bus lines
• Ensures signal integrity through an extended ±15V common-mode range
• Supports reliable half-duplex communication for RS-422 and RS-485 standards

Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation interfaces

Procurement Notes

Verify the specific suffix T7A indicates reel packaging when sourcing. Confirm the manufacturer part number matches exactly to ensure correct OVP and CMR specifications. Check RoHS compliance status if required by project regulations. Ensure the supplier is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when 40V fault protection and ±15V common-mode range are critical requirements. It is suitable for applications requiring 1 Mb/s data rates with standard 3V or 5V logic levels. Consider the SOIC-8 package size for PCB layout constraints compared to smaller alternatives.

Part Context

This part belongs to the ISL31475 series of fault-protected differential transceivers. It shares functional similarities with other members like the ISL31470E but offers specific protection ratings. The series is designed for harsh electrical environments where standard transceivers might fail due to high voltage spikes or noise.

Replacement Considerations

Direct substitutes include the ISL31475EIBZ for tape-and-reel variations without the T7A suffix designation. Other family members such as the ISL31470E may offer similar functionality but require verification of specific OVP and CMR limits before substitution.
