ISL3158EIUZ

Overview

The ISL3158EIUZ is a half-duplex RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It operates on a single 5V supply and supports data rates up to 20 Mb/s. The device features ±15kV IEC61000 ESD protection on the bus pins and includes full fail-safe receiver functionality. It utilizes an MSOP-8 surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides ±15kV IEC61000 ESD protection on RS-485 I/O pins for enhanced robustness in harsh environments.
• Incorporates full fail-safe design ensuring a logic high output when inputs are floating, shorted, or undriven.
• Supports hot-plug operation with three-state outputs during power-up to prevent bus contention.

Applications

• Industrial automation networks requiring reliable half-duplex communication
• Remote utility meter reading systems utilizing RS-485 buses
• Building automation and control systems

Procurement Notes

Verify the specific suffix 'EIUZ' against the manufacturer's current datasheet to confirm the MSOP-8 package and industrial temperature grade. Ensure compliance with RoHS directives as indicated in official documentation before procurement.

Selection Notes

Select this component for applications requiring high-speed data transmission up to 20 Mb/s with integrated ESD protection. It is suitable for designs needing true 1/8 unit load capability to support multiple nodes on a single bus without repeaters.

Part Context
