ISL31495EIBZ-T7A

Overview

The ISL31495EIBZ-T7A is a half-duplex RS-485/RS-422 transceiver in an 8-pin SOIC package. It operates at data rates up to 1 Mbps with a supply voltage range of 4.5V to 5.5V. The device features ±60V fault protection and an extended common mode range of ±25V. Quiescent current is typically 2.3 mA, with shutdown current at 10 µA. It supports -40°C to +85°C operation.

Feature Summary

• Half-duplex architecture with integrated driver and receiver sharing bus pins
• Extended common mode voltage tolerance exceeding standard RS-485 requirements
• Full fail-safe receiver design ensuring defined output states during idle or fault conditions

Applications

• Utility meters and automated meter reading systems
• PROFIBUS and fieldbus networks
• Industrial process control networks

Procurement Notes

Verify the specific suffix T7A indicates tape and reel packaging as per manufacturer documentation. Confirm RoHS compliance status and moisture sensitivity level classification before procurement. Ensure the ordering part number matches the required 8-lead SOIC package variant for your assembly process.

Selection Notes

Select this component for designs requiring robust fault protection on the RS-485 bus. The half-duplex configuration suits applications where bidirectional communication shares a single pair. Verify that the 1 Mbps data rate meets system timing requirements and that the 8-pin footprint fits the PCB layout constraints.

Part Context

This device belongs to the ISL3149xE family of fault-protected transceivers. It shares architectural similarities with the ISL31492E and ISL31498E but differs in duplex mode and maximum data rate specifications. The family emphasizes high noise immunity through elevated differential output voltages.

Replacement Considerations

ISL31492EIBZ-T7A: Half-duplex, 250 kbps. ISL31498EIBZ-T7A: Half-duplex, 15 Mbps.
