ISL32478EIBZ-T7A

Overview

The ISL32478EIBZ-T7A is a fault-protected RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It features an 8-pin SOIC package and supports data rates up to 10 Mbps. The device operates within a supply voltage range of 3V to 5.5V and functions across a temperature range of -40°C to +85°C. Key electrical specifications include ±15V common-mode rejection, ±16.5kV ESD protection, and overvoltage protection on the bus pins.

Feature Summary

• Integrated overvoltage protection on bus pins to withstand high-voltage faults
• Extended common-mode range capability for robust signal integrity in noisy environments
• High electrostatic discharge (ESD) protection rating for enhanced reliability

Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific packaging variants such as tape and reel configurations. Ensure that the procurement source provides valid traceability documentation to mitigate counterfeiting risks during acquisition.

Selection Notes

Select this transceiver when extended common-mode voltage tolerance and bus pin overvoltage protection are required. It is suitable for applications demanding high ESD immunity and reliable communication over long distances in electrically noisy industrial settings compared to standard interface devices.

Part Context

This component belongs to the ISL3247xE family of fault-protected transceivers designed for RS-485 and RS-422 serial communication standards. It integrates advanced protection features into a compact surface-mount package, addressing durability requirements in harsh operational environments where standard transceivers might fail due to electrical stress.

Replacement Considerations

Consult official Renesas cross-reference lists for verified substitutes. Direct replacements must maintain identical protocol support, package dimensions, and protection ratings to ensure circuit compatibility without redesign.
