ISL3159EIUZ

Overview

The ISL3159EIUZ is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates with a single 5 V supply and supports data transmission rates up to 40 Mb/s. The device integrates one driver and one receiver within an MSOP-8 surface-mount package. It functions reliably across an industrial temperature range from -40 °C to +85 °C. The component provides differential output signals for robust communication in noisy environments.

Feature Summary

• Supports high-speed data transmission up to 40 Mb/s
• Complies with IEC 61000-4-2 electrostatic discharge standards
• Operates on a single 5 V power supply

Applications

• Industrial sensor networks
• Building automation systems
• Factory automation control loops

Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Confirm moisture sensitivity level handling procedures during assembly to prevent damage.

Selection Notes

Select this model when a 5 V supply voltage is required for RS-485 communication. Choose this part over lower-speed variants if data rates approaching 40 Mb/s are necessary. Verify that the MSOP-8 footprint aligns with the printed circuit board layout constraints.

Part Context

This component belongs to the ISL3159E series of high-speed transceivers. It serves as a bridge between serial communication protocols and physical bus lines. The device is designed for applications requiring reliable data integrity in electrically noisy industrial settings.

Replacement Considerations

The ISL3159EIRZ offers identical electrical performance but utilizes a 10-DFN package instead of the MSOP-8 form factor. Verify pin compatibility and thermal dissipation requirements before substituting.
