ISL3171EIUZ-T

Drivers, Receivers, Transceivers Overview

The ISL3171EIUZ-T is a single RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates on a single 3.3V supply and supports data rates up to 250 kb/s. The device features full duplex communication with one driver and one receiver in an 8-MSOP package. It provides ±15kV IEC61000 ESD protection on RS-485 I/O pins and >7kV HBM protection elsewhere. Operating temperature ranges from -40°C to +85°C, with a quiescent current of 510 µA.

Drivers, Receivers, Transceivers Feature Summary

• IEC61000 standard ESD protection on RS-485 I/O pins
• Full fail-safe receiver design for floating or shorted inputs
• True 1/8 unit load capability supporting high node counts

Drivers, Receivers, Transceivers Applications

• Industrial control systems
• Remote utility meter reading networks
• Balanced communication buses requiring RS-485 compliance

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm RoHS3 compliance status through official datasheets. Ensure the MSOP-8 package dimensions match PCB footprint requirements. Validate that the 250 kb/s speed meets system timing constraints.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single transceiver with low power consumption is required. The true 1/8 unit load allows connecting up to 256 devices without repeaters. Verify compatibility with 3.3V logic levels. Consider the thermal shutdown feature for overload protection in harsh environments.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL317xE series of low-power, high-speed RS-485/RS-422 transceivers. The series includes variants with different duplex configurations and slew rate limitations. The ISL3171E specifically offers full duplex operation with integrated ESD protection.

Drivers, Receivers, Transceivers Replacement Considerations

Check for ISL3172E or ISL3175E if half-duplex or different data rates are needed. Verify pinout compatibility before substituting with other RS-485 transceivers. Ensure equivalent ESD protection levels are maintained.
