ISL32273EIBZ-T

Drivers, Receivers, Transceivers 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.

Drivers, Receivers, Transceivers 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.

Drivers, Receivers, Transceivers 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.

Drivers, Receivers, Transceivers 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.

Drivers, Receivers, Transceivers 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.

Drivers, Receivers, Transceivers Part Context
