ISL3174EIUZ

Drivers, Receivers, Transceivers Overview

The ISL3174EIUZ is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation, housed in an MSOP-8 surface-mount package. It operates at a fixed supply voltage of 3.3 V with a maximum data rate of 500 kb/s. The device features one driver and one receiver, drawing a typical operating current of 510 µA. It supports a full fail-safe receiver design and functions within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• IEC-61000 ESD protection on RS-485 I/O pins
• Full fail-safe receiver for open or shorted bus conditions
• Low power consumption suitable for battery applications

Drivers, Receivers, Transceivers Applications

• Remote utility meter reading systems
• Industrial control networks
• Building automation systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity through authorized Renesas distributors or certified suppliers. Confirm the specific manufacturing lot date code against project requirements. Ensure the MSOP-8 package matches the PCB footprint exactly. Check for RoHS compliance documentation if required by regional regulations. Validate that the 3.3V supply rail aligns with system power specifications before integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a low-speed, low-power RS-485 interface is required in a compact form factor. The 500 kb/s data rate limits suitability for high-bandwidth applications. The true 1/8 unit load capability allows for extensive bus topologies without repeaters. Consider the MSOP-8 package constraints regarding thermal dissipation and soldering profiles during design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL317xE series of ±15kV ESD protected transceivers. It shares architectural similarities with other members like the ISL3172E but differs in data rate specifications. The series emphasizes robustness in noisy industrial environments while maintaining minimal power draw.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other ISL317xE variants such as ISL3172EIUZ or ISL3175EIUZ, provided the data rate and pinout compatibility are verified. Cross-referencing with newer Renesas RZ family equivalents may be necessary for long-term availability.
