ISL3170EIUZ-T

Drivers, Receivers, Transceivers Overview

The ISL3170EIUZ-T is a single RS-485/RS-422 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 ±15kV IEC61000 ESD protection on the bus pins and incorporates full fail-safe receiver functionality. It presents a true 1/8 unit load, allowing up to 256 devices on the network. Key electrical parameters include a maximum quiescent current of 800 µA and an ultra-low shutdown current of 10 nA. The component operates within a temperature range of -40°C to +85°C and is housed in a 10-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• IEC61000 ESD protection rated at ±15kV on RS-485 I/O pins
• Full fail-safe design ensures logic high output when inputs are floating or shorted
• Hot plug circuitry maintains three-state outputs during power-up stabilization
• Slew rate limited drivers reduce electromagnetic interference and signal reflections

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date with your project timeline to account for any potential manufacturing changes or lifecycle updates.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low power consumption and robust ESD protection in noisy environments. The slew-rate limited driver is suitable for reducing EMI in multidrop configurations. Verify that the 250 kb/s data rate meets system timing requirements and that the 3.3V supply voltage aligns with the host controller logic levels.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL317xE series of RS-485/RS-422 transceivers. The series includes variants with different data rates and duplex configurations. The 'E' suffix typically denotes extended industrial temperature ranges, while the 'T' indicates reel packaging. This specific model focuses on low-speed, low-power applications within the broader interface IC portfolio.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible substitutes within the ISL317xE family, such as the ISL3171E or ISL3173E, if higher data rates or different pinouts are required. Verify that alternative components maintain the same 1/8 unit load characteristic to ensure compatibility with existing network topologies.
