ISL3170EIUZ

Overview

The ISL3170EIUZ is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates on a single 3.3V supply and supports data rates up to 250 kb/s. The device features ±15kV IEC61000 ESD protection on the bus pins and full fail-safe receiver inputs. It utilizes a true 1/8 unit load, allowing up to 256 devices on the network. The component is housed in an MSOP-10 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• IEC61000 ESD protection on RS-485 I/O pins
• Full fail-safe receiver design for floating or shorted inputs
• True 1/8 unit load capability for high node count networks
• Slew rate limited drivers to reduce EMI

Applications

• Remote utility meter reading systems
• High node count field bus networks
• Security camera networks

Procurement Notes

Verify the specific suffix 'U' indicates the MSOP-10 package configuration and 'Z' denotes lead-free compliance. Confirm the 'E' suffix corresponds to the industrial temperature range specifications. Ensure the ordering code matches the exact datasheet revision required for your design implementation.

Selection Notes

Select this component when designing RS-485 networks requiring high node density without repeaters. The low quiescent current and slew rate limiting make it suitable for noise-sensitive environments. Verify that the 3.3V logic levels align with the host microcontroller interface requirements.

Part Context

This part belongs to the ISL317xE family of transceivers designed for balanced communication standards. The series includes variants with different duplex configurations and speed options. The ISL3170E specifically provides full-duplex functionality with separate receive and transmit pins.

Replacement Considerations

ISL3170EIUZ-T is the tape-and-reel version of the same component. Other family members like ISL3171E offer half-duplex configurations.
