ISL32273EIBZ-T

Overview

The ISL32273EIBZ-T is a quad receiver integrated circuit from the Renesas ISL32273E series, designed for RS-422 and RS-485 communication interfaces. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 20 Mb/s. The device features robust electrostatic discharge (ESD) protection rated at ±15 kV according to the Human Body Model (HBM). It functions reliably across an extended industrial temperature range from -40°C to +85°C. The component is housed in a 16-lead Small Outline Integrated Circuit (SOIC) package with a narrow body width.

Feature Summary

• Provides four independent differential receivers optimized for high-speed serial data transmission.
• Integrates high-level ESD protection to safeguard sensitive input pins against electrical stress.
• Supports flexible power supply configurations compatible with both 3.3 V and 5 V logic systems.

Applications

• Industrial automation networks requiring reliable RS-485 multi-drop communication.
• Building management systems utilizing RS-422 point-to-point or multi-point links.
• Data acquisition modules operating in electrically noisy environments.

Procurement Notes

Verify the specific suffix 'IBZ' against the manufacturer's current datasheet to confirm the package type and tape-and-reel configuration. Ensure that the ordering quantity aligns with the standard reel size specified by Renesas Electronics. Cross-reference the RoHS compliance status with the latest environmental declaration documents provided by the supplier.

Selection Notes

Select this component when a quad receiver topology is required for RS-422 or RS-485 bus architectures. It is suitable for designs needing high noise immunity and wide common-mode voltage ranges. Consider the SOIC-16 footprint during PCB layout planning to ensure adequate spacing for the narrow body package dimensions.

Part Context

This part belongs to the ISL3227xE family of interface controllers, which are engineered for robust performance in harsh industrial settings. The series typically includes complementary transceivers and drivers, allowing for scalable design implementations. Renesas utilizes Intersil heritage technology to deliver high reliability and low power consumption characteristics.

Replacement Considerations

Check for direct pin-compatible alternatives within the ISL3227xE series, such as the ISL32273EFVZ for different packaging options. Verify if newer generation parts from Renesas offer enhanced specifications while maintaining functional compatibility.
