ISL32273EFVZ

Overview

The ISL32273EFVZ is a quad RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 10 Mb/s. The device features ±15 kV ESD protection on the bus pins, ensuring robust performance in harsh environments. It is housed in a 16-lead Quad Flat Package (QFP) with a maximum operating temperature of 125°C.

Feature Summary

• Integrated ±15 kV electrostatic discharge protection on differential bus lines for enhanced reliability.
• Supports high-speed data transmission at rates up to 10 Mb/s for efficient communication.
• Compatible with standard 3.0 V to 5.5 V power supplies for flexible system integration.

Applications

• Industrial control systems requiring reliable serial communication.
• Building automation networks utilizing RS-422 or RS-485 protocols.
• Data acquisition systems operating in electrically noisy environments.

Procurement Notes

Verify the specific package variant and manufacturing date code against current Renesas documentation before procurement. Confirm that the component meets all required environmental specifications for the intended application environment. Ensure compatibility with existing board layouts and signal integrity requirements.

Selection Notes

Select this component when a quad driver configuration is required for RS-422 or RS-485 networks. Consider the 125°C maximum junction temperature for high-thermal applications. Verify that the 10 Mb/s data rate aligns with system timing constraints and that the QFP package fits the available PCB footprint.

Part Context

This part belongs to the ISL3227xE series of interface ICs from Renesas. It provides a complete solution for multi-drop communication networks. The series is designed to offer high noise immunity and low power consumption compared to older generation devices.

Replacement Considerations

Check for direct pin-compatible alternatives within the ISL3227x family. Verify if newer Renesas generations offer improved ESD ratings or lower power consumption while maintaining the same electrical characteristics and package dimensions.
