ISL31496EIBZ-T7A

Overview

The ISL31496EIBZ-T7A is a full-duplex, fault-protected RS-485/RS-422 differential transceiver manufactured by Renesas Electronics Corporation. It operates on a single 5V supply (4.5V to 5.5V) and supports data rates up to 15Mbps. The device features ±60V bus pin fault protection and an extended common mode range of ±25V. It includes hot plug circuitry, low power shutdown mode with 10µA current consumption, and a 14-lead SOIC package.

Feature Summary

• Fault protected RS-485 bus pins withstand up to ±60V
• Extended common mode voltage tolerance of ±25V
• Full fail-safe receiver design for open, shorted, or idle bus conditions
• Hot plug functionality maintains three-state outputs during power transitions

Applications

• Utility meters and automated meter reading systems
• PROFIBUS and field bus networks
• Security camera networks
• Industrial process control networks

Procurement Notes

Verify the component status as discontinued or obsolete through official manufacturer channels before procurement planning. Confirm availability of parameter-equivalent replacement parts such as the ISL32496 series if active sourcing is required. Ensure compliance with RoHS standards and check specific moisture sensitivity levels for storage and handling requirements.

Selection Notes

Select this component for applications requiring high noise immunity and robust operation in electrically noisy environments. The extended common mode range and fault protection make it suitable for long-distance communication buses. Verify that the 14-pin SOIC package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the ISL3149xE family of fault-protected transceivers designed to exceed standard RS-485 specifications. It shares architectural similarities with other variants like the ISL31490E and ISL31493E but offers higher speed capabilities. The family emphasizes ruggedness for industrial automation and building control applications.

Replacement Considerations

The ISL32496EIUZ-T is listed as a parameter-equivalent replacement.
