ISL3159EFBZ-T

Overview

The ISL3159EFBZ-T is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating current of 4 mA at 5 V. The device supports data transmission rates up to 40 Mb/s and functions reliably across an extended temperature range from -40°C to +125°C. Housed in an SOIC-8 surface-mount package, it integrates one driver and one receiver for differential output signaling. This component is designed for robust communication in industrial environments requiring high noise immunity.

Feature Summary

• Supports data rates up to 40 Mb/s for high-speed serial communication
• Operates over an extended industrial temperature range of -40°C to +125°C
• Provides high electromagnetic interference (EMI) immunity through slew-rate-limited drivers

Applications

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

Procurement Notes

Verify the specific suffix 'FBZ' against official Renesas documentation to confirm the SOIC-8 package and tape-and-reel delivery format. Ensure the procurement channel provides valid traceability for moisture sensitivity level handling requirements. Confirm that the delivered units match the exact part number designation to avoid compatibility issues with existing circuit designs.

Selection Notes

Select this component when a half-duplex RS-485 interface is required with support for data rates up to 40 Mb/s. The wide operating temperature range makes it suitable for harsh industrial environments. Verify that the system power supply aligns with the 4.5 V to 5.5 V specification and that the PCB layout accommodates the SOIC-8 footprint.

Part Context

This part belongs to the ISL3159E series of RS-485/RS-422 interface ICs. The series includes variants with different packaging options such as MSOP-8 and DFN packages. All members share core electrical characteristics including 40 Mb/s speed and high ESD protection capabilities, tailored for reliable data transmission in noisy environments.

Replacement Considerations

Cross-reference with other ISL3159E series parts like ISL3159EIUZ-T or ISL3159EIBZ if package changes are acceptable. Verify pinout compatibility before substitution. Ensure thermal performance meets requirements if replacing with a variant having a different thermal dissipation profile.
