ISL33001IRT2Z

Signal Buffers, Repeaters, Splitters Overview

The ISL33001IRT2Z is a single-channel I2C bus buffer manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of +2.3V to +5.5V and supports data rates exceeding 400kHz. The device features rise time acceleration, hot swap capability, and logic level shifting for mixed-voltage applications. It provides ±6kV Class 3 HBM ESD protection on all pins and ±12kV HBM protection on SDA/SCL lines. Operating temperatures range from -40°C to +85°C. The component is housed in an 8-lead TDFN (3mm x 3mm) package with an exposed pad, designed for surface mount installation.

Signal Buffers, Repeaters, Splitters Feature Summary

• Integrates rise time accelerator circuitry to reduce passive pull-up resistor power consumption while enhancing data rate performance.
• Includes dedicated hot swap protection circuitry to prevent damage to data and clock lines during insertion into live backplanes.
• Provides bidirectional buffering that extends bus capacitance beyond the standard I2C specification limit of 400pF.
• Supports logic level translation for applications utilizing mixed power supply voltages.

Signal Buffers, Repeaters, Splitters Applications

• I2C bus expansion and capacitance buffering
• Server rack isolation in telecommunications, data communication, and computer server systems
• Hot swap circuit board insertion and bus isolation

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'IRT2Z' against the manufacturer's official datasheet to confirm the tape and reel packaging configuration and temperature grade. Ensure the ordering documentation explicitly references the Renesas or Intersil part number to avoid substitution errors with similar buffered components. Cross-reference the moisture sensitivity level requirements prior to assembly processing.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when a single-channel I2C buffer is required for systems operating between 2.3V and 5.5V. It is suitable for designs needing extended bus capacitance handling and protection against hot insertion events. Consider the TDFN-EP-8 package constraints for thermal management and PCB layout space compared to MSOP alternatives.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the ISL3300x family of I2C bus buffers, which also includes dual-channel variants like the ISL33002 and ISL33003. These devices share common architectural features such as rise time acceleration and hot swap capabilities but differ in channel count. The family addresses the need for robust signal integrity in complex multi-drop I2C networks.
