ISL32433EIBZ

Overview

The ISL32433EIBZ is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mb/s. The device features one driver and one receiver, providing full-duplex communication capabilities. It is housed in an 8-lead SOIC package with a maximum operating temperature of +85°C and a minimum of -40°C. Key electrical specifications include a common-mode rejection ratio of 4000 V/ms and input protection up to ±40 V.

Feature Summary

• Integrated overvoltage protection on both transmit and receive pins to safeguard against line faults.
• Fail-safe circuitry ensures the receiver output defaults to a high logic state when inputs are open or disconnected.
• Low power consumption design includes a shutdown mode that minimizes current draw during idle periods.

Applications

• Industrial automation networks requiring robust RS-485 communication.
• Building automation systems utilizing RS-422 point-to-point links.
• Metering infrastructure for utility data collection.

Procurement Notes

Verify the specific suffix 'EIBZ' confirms RoHS compliance and lead-free status as per manufacturer standards. Confirm package type matches the 8-SOIC specification. Check for obsolescence notices or lifecycle changes from Renesas before finalizing procurement plans.

Selection Notes

Select this component for designs requiring single-channel differential communication with high noise immunity. Ensure the system voltage aligns with the 3V to 5.5V operational range. Consider thermal management if operating near the upper temperature limit in enclosed industrial enclosures.

Part Context

This part belongs to the ISL3243xE family of interface ICs designed for reliable serial communication in noisy environments. It complements other transceivers in the portfolio by offering a balance of speed, protection, and low power consumption suitable for standard industrial protocols.

Replacement Considerations
