ISL3158EIUZ-T

Overview

The ISL3158EIUZ-T is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics. It operates with a single 5 V supply and supports data rates up to 20 Mb/s. The device integrates one driver and one receiver in an MSOP-8 surface-mount package. It provides high common-mode rejection and complies with IEC 61000 ESD standards. The component functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• IEC 61000-compliant electrostatic discharge protection for robust signal integrity
• High common-mode rejection capability for reliable noise immunity
• Slew-rate limited drivers to minimize electromagnetic interference

Applications

• Industrial communication networks requiring RS-485 connectivity
• Building automation systems utilizing differential signaling
• Data acquisition modules in harsh electrical environments

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing components. Confirm the manufacturer designation as Renesas Electronics, formerly Intersil, to ensure authenticity. Check RoHS compliance status through official datasheets prior to integration into regulated assemblies.

Selection Notes

Select this model for applications requiring 20 Mb/s throughput on a 5 V bus. Ensure the MSOP-8 footprint matches the PCB layout constraints. Compare against the ISL3156E series if ten-pin packaging is preferred for identical performance specifications.

Part Context

This component belongs to the ISL3158E family of high-performance RS-485 transceivers. It shares functional similarities with the ISL3150E and ISL3156E series but differs in package configuration and pinout. The product line emphasizes durability and signal fidelity for industrial data links.

Replacement Considerations

The ISL3156EIUZ-T serves as a pin-compatible alternative in a 10-pin MSOP package. Verify voltage levels and data rate requirements before substituting with other RS-485 interface ICs from the same manufacturer.
