ISL31496EIBZ-T

Overview

The ISL31496EIBZ-T is a full-duplex, fault-protected RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It operates on a single 4.5V to 5.5V supply with a typical quiescent current of 2.3mA and supports data rates up to 15Mbps. The device features ±60V bus pin fault protection and an extended common mode range of ±25V. It is housed in a 14-lead SOIC package (M14.15) and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Full fail-safe receiver design ensures logic high output when inputs are floating, shorted, or idle.
• Integrated hot plug circuitry maintains three-state outputs during power-up and power-down sequences.
• High transient overvoltage tolerance provides robustness against electrical faults.

Applications

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

Procurement Notes

Verify the component status as discontinued or obsolete through official manufacturer channels before procurement planning. Confirm that the specific ordering suffix matches the required tape and reel specifications for surface mount assembly processes.

Selection Notes

Select this model for applications requiring full-duplex communication at speeds up to 15Mbps. Ensure the system environment accommodates the specified ±25V common mode voltage range and requires the 14-pin SOIC footprint for integration.

Part Context

This component belongs to the ISL3149xE series of fault-protected differential transceivers designed to exceed standard RS-485 and RS-422 requirements. The series includes variants with different duplex modes and data rate capabilities, all sharing the same core fault protection architecture.

Replacement Considerations

Public confirmed substitute part numbers include the ISL32496E series. Verify compatibility regarding package dimensions and electrical parameters before substitution.
