ISL32177EFRZ

Overview

The ISL32177EFRZ is a low-power RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It supports data rates up to 64 Mbps and features ±15 kV ESD protection on both the bus and I/O pins. The device operates from a single 3 V to 5.5 V supply and includes a fail-safe receiver to ensure a high output state when inputs are open. Packaged in a compact 4 mm x 4 mm QFN, it is designed for industrial applications requiring robust communication interfaces.

Feature Summary

• Integrated ±15 kV ESD protection on bus and I/O lines
• Fail-safe receiver ensures defined output during idle states
• Low power consumption with shutdown mode capability

Applications

• Industrial control systems
• Building automation networks
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'EFRZ' against the official datasheet to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for the 4x4 QFN package. Confirm RoHS compliance status if required by project specifications before finalizing procurement orders.

Selection Notes

Select this component when high-speed 64 Mbps communication is required alongside strong ESD immunity. Compare against standard RS-485 transceivers if lower speed suffices. Verify that the 3 V to 5.5 V supply range matches the system voltage rails. Consider the QFN package size constraints during layout planning.

Part Context

This part belongs to the ISL3217xE family of high-speed RS-422/RS-485 transceivers. It shares functional similarities with other members like the ISL32173E and ISL32175E, differing primarily in data rate capabilities and specific pin configurations. The family targets reliable serial communication in noisy environments.

Replacement Considerations

Check for direct cross-references such as MAX32177 or SP32177 equivalents. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Ensure the replacement supports the same 64 Mbps rate and ESD protection levels.
