ISL32483EIBZ-T7A

Overview

The ISL32483EIBZ-T7A is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates on a single 5 V supply and supports data rates up to 1 Mb/s. The device features overvoltage protection on the bus pins, allowing operation with signals exceeding the supply voltage. It is housed in an 8-lead SOIC package and functions within a temperature range of -40°C to +85°C. Key electrical parameters include a 2.3 mA operating current and a shutdown mode for power conservation.

Feature Summary

• Integrated overvoltage protection on differential bus pins
• Low-power shutdown mode capability
• Compliant with RS-485 communication standards

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 moisture sensitivity level prior to assembly. Check for obsolescence notices or product change notifications that may affect long-term availability. Ensure packaging integrity matches specified reel or cut tape requirements for surface mount processing.

Selection Notes

Select this component when designing RS-485 interfaces requiring robust overvoltage tolerance on the bus lines. It is suitable for applications needing low standby current via shutdown functionality. Verify that the 5 V supply voltage aligns with system power rails. Consider the 8-lead SOIC package dimensions for PCB layout constraints compared to other available packages in the series.

Part Context

This part belongs to the ISL3248xE family of high-performance RS-485 transceivers from Renesas. The family focuses on providing reliable communication in electrically noisy industrial environments. The specific suffix indicates the tape and reel packaging format for automated assembly processes.

Replacement Considerations

ISL32483EIBZ is the non-tape-and-reel variant of the same component.
