ISL3155EIBZR5172

Overview

The ISL3155EIBZR5172 is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates on a single 5V supply and supports data rates up to 20Mbps. The device features ±15kV IEC61000 ESD protection on the bus pins and full fail-safe receiver functionality. It utilizes a true 1/8 unit load, allowing up to 256 devices on the network. The component includes thermal shutdown and current limiting for driver overload protection.

Feature Summary

• Provides robust ±15kV IEC61000 ESD protection on RS-485 I/O pins
• Ensures reliable communication with full fail-safe receiver design
• Supports high-density networks with true 1/8 unit load capability

Applications

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

Procurement Notes

Verify the specific suffix R5172 against official Renesas documentation to confirm reel packaging specifications. Ensure the operating voltage matches the 5V requirement of this variant. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when 5V operation is required instead of the 3.3V variants in the ISL317xE family. The 1/8 unit load feature makes it suitable for large-scale bus topologies. Verify that the package type meets the board space constraints of the target application design.

Part Context

This part belongs to the ISL315xE series of differential transceivers designed for balanced communication lines. It complements the broader Renesas portfolio of interface solutions used in industrial and commercial applications requiring reliable serial data transmission over long distances.

Replacement Considerations

Direct substitutes include other ISL315xE variants such as ISL3152E or ISL3156E if pin compatibility allows. Verify electrical parameters like supply voltage and data rate before swapping components in existing designs.
