ISL31470EIBZ-T

Overview

The ISL31470EIBZ-T is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It operates with a fixed 5 V supply voltage and supports data rates up to 5 Mb/s. The device features overvoltage protection on the I/O pins, rated for ±15 V common-mode rejection. It is housed in a 14-lead SOIC package and functions within an operating temperature range of -40°C to +85°C. The unit draws 4.5 mA of operating current and provides differential output signals.

Feature Summary

• Integrated overvoltage protection on receiver and driver I/O pins
• Supports full-duplex RS-422 and half-duplex RS-485 communication protocols
• High electromagnetic immunity via ±15 V common-mode rejection capability

Applications

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

Procurement Notes

Verify the manufacturer part number ISL31470EIBZ-T against official Renesas documentation to confirm pinout and electrical specifications. Ensure the SOIC-14 package variant matches the design requirements. Check for RoHS compliance status as indicated in the datasheet. Confirm moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this component when a single transceiver with robust overvoltage protection is required for 5 V systems. It is suitable for applications needing high common-mode noise immunity. Compare against the ISL32470EIBZ-T if higher data rates are necessary. Verify that the 5 Mb/s speed meets the network timing constraints.

Part Context
