ISL3155EIUZ

Overview

The ISL3155EIUZ is a single RS-485 transceiver manufactured by Renesas Electronics Corporation, housed in an MSOP-10 surface-mount package. It supports data transmission rates up to 1 Mb/s and operates on a single 5 V power supply. The device functions within an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a maximum supply voltage of 5 V and a typical operating supply current of 600 µA. It integrates ESD protection and features a shutdown mode for power conservation.

Feature Summary

• Supports RS-485 differential communication standards with full fail-safe receiver operation
• Integrates ESD protection circuitry on I/O pins
• Includes a low-power shutdown mode to minimize quiescent current consumption

Applications

• Industrial automation control networks
• Building automation systems
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'UIZ' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and RoHS compliance status. Confirm that the MSOP-10 footprint matches the target PCB design requirements before finalizing procurement orders.

Selection Notes

Select this component when a single RS-485 transceiver with moderate speed (1 Mb/s) and 5 V operation is required. Ensure the application does not demand higher data rates or lower supply voltages, as other variants in the series may be more suitable for those specific constraints.

Part Context

This part belongs to the ISL3155E family of RS-485 transceivers from Renesas. The family provides robust communication interfaces for half-duplex applications. The MSOP-10 package offers a compact solution for space-constrained designs compared to larger through-hole packages.

Replacement Considerations

Check for direct pin-compatible replacements within the same Renesas ISL3155E series. Verify if alternative manufacturers offer equivalent RS-485 transceivers with matching 1 Mb/s speeds and 5 V supply requirements.
