ISL3159EIUZ-T7A

Overview

The ISL3159EIUZ-T7A is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics. It operates at data rates up to 40 Mb/s with a fixed 5 V supply voltage. The device features one driver and one receiver in an MSOP-8 surface-mount package. It supports an operating temperature range from -40°C to +85°C and draws 4 mA of quiescent current. The component provides differential outputs and complies with IEC61000 standards for electromagnetic immunity.

Feature Summary

• Supports high-speed data transmission up to 40 Mb/s on RS-422 and RS-485 networks.
• Provides robust electromagnetic interference immunity compliant with IEC61000 standards.
• Operates exclusively on a 5 V power supply rail.

Applications

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

Procurement Notes

Verify the specific suffix T7A indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Renesas Electronics, as Intersil was previously associated with this product line. Ensure the MSOP-8 package matches the design requirements. Check RoHS compliance status through official documentation before finalizing procurement.

Selection Notes

Select this component for applications requiring 5 V operation and 40 Mb/s throughput. It is suitable where IEC61000 ESD protection is mandatory. Compare against the ISL3159EIUZ tube version if reel packaging is not required. Verify that the MSOP-8 footprint fits the PCB layout constraints.

Part Context

This part belongs to the ISL3159E series of high-speed transceivers. It shares the core electrical specifications with other variants like the ISL3159EIUZ but differs in shipping configuration. The series is designed for reliable communication in noisy industrial environments.

Replacement Considerations

The ISL3159EIUZ is a direct functional equivalent differing only in tube packaging. Other RS-485 transceivers may require voltage level or speed adjustments.
