ISL32273EFVZ-T

Overview

The ISL32273EFVZ-T is an RS-422/RS-485 interface integrated circuit manufactured by Renesas Electronics. It features four receivers and operates within a supply voltage range of 3 V to 5.5 V. The device supports data rates up to 20 Mb/s and includes 15 kV ESD protection. It functions in temperatures from -40°C to +125°C, drawing 5.5 mA during operation. The component is housed in a 16-lead TSSOP package.

Feature Summary

• Four-channel receiver configuration for RS-422/RS-485 communication
• High-speed data transmission capability up to 20 Mb/s
• Robust electrostatic discharge protection rated at 15 kV
• Extended industrial temperature range support

Applications

• Industrial control systems requiring reliable serial communication
• Building automation networks utilizing RS-485 protocols
• Data acquisition systems operating in electrically noisy environments

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer documentation prior to integration. Ensure the 16-lead TSSOP footprint matches the target PCB layout requirements exactly.

Selection Notes

Select this component specifically for applications requiring multiple receivers rather than transceivers. Verify that the 20 Mb/s speed requirement aligns with system timing constraints. Consider the 5.5 mA quiescent current against total power budget limitations in the design.

Part Context

This part belongs to the ISL32273E series of RS-422/RS-485 interface devices. It serves as a dedicated receiver solution within Renesas's broader portfolio of industrial communication components. The series is designed for high-reliability applications in harsh electrical environments.

Replacement Considerations

Check for ISL32273EFBZ variants if SOIC packaging is required instead of TSSOP. Verify compatibility with ISL32272E series parts only if driver functionality is also needed, noting the different internal architecture.
