ISL31496EIBZ

Overview

The ISL31496EIBZ is a full-duplex RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It operates on a single 5V supply and supports data rates up to 25 Mbps. The device features ±60V fault protection on bus pins and an extended common mode range of ±25V. It includes hot plug circuitry, low power shutdown mode with 10µA current consumption, and full fail-safe receiver design. Packaged in a 14-lead SOIC (M14.15), it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Extended common mode voltage tolerance up to ±25V for robust operation in high noise environments
• Bus pin fault protection rated at ±60V with transient overvoltage tolerance of ±80V
• Full fail-safe receiver ensures logic high output when inputs are floating or shorted
• Hot plug capability keeps outputs in three-state during power-up and power-down

Applications

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

Procurement Notes

Verify the specific ordering suffix 'BZ' indicates RoHS compliance and lead-free packaging as per manufacturer specifications. Confirm the package drawing M14.15 matches the required PCB footprint. Ensure the moisture sensitivity level requirements align with assembly processes. Check for any recent product change notices regarding manufacturing sites or material sets.

Selection Notes

Select this component for applications requiring full-duplex communication with high data rates up to 25 Mbps. It is suitable for environments with significant common mode noise due to the ±25V tolerance. Consider the 14-pin SOIC package size for board space constraints. Verify that the system requires separate driver and receiver lines rather than half-duplex multiplexing.

Part Context

This part belongs to the ISL3149xE series of fault-protected, 5V differential transceivers. It shares core electrical characteristics with siblings like the ISL31490E and ISL31493E but differs in duplex configuration and data rate capabilities. The series is designed to exceed standard RS-485 and RS-422 requirements for ruggedness.

Replacement Considerations

Consult the ISL32490E datasheet for exact replacement options if newer designs are preferred. Verify pin compatibility and electrical parameters against existing designs before substitution.
