ISL32485EIBZ-T7A

Overview

The ISL32485EIBZ-T7A is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics. It operates on a single 5 V supply and supports data rates up to 1 Mb/s. The device features overvoltage protection (OVP) on the bus pins, high electrostatic discharge (ESD) protection with polarity tolerance, and a shutdown mode for low power consumption. It is housed in an 8-lead SOIC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated overvoltage protection on differential bus lines
• High ESD protection with input polarity tolerance
• Low-power shutdown capability

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level before storage. Check for obsolescence notices or lifecycle changes from the manufacturer prior to finalizing procurement plans.

Selection Notes

Select this component for designs requiring robust bus protection and 5 V operation. Ensure compatibility with existing RS-485 network protocols. Verify that the 1 Mb/s speed meets system requirements and that the SOIC-8 footprint fits the PCB layout constraints.

Part Context

This part belongs to the ISL32485E series of ruggedized transceivers. It shares functional similarities with other members of the family but is distinguished by its specific 5 V supply requirement and high ESD characteristics. It serves as a reliable interface solution for noisy industrial environments.
