ISL33002IUZ

Signal Buffers, Repeaters, Splitters Overview

The ISL33002IUZ is a dual-channel I2C bus buffer manufactured by Renesas Electronics. It operates within a supply voltage range of +2.3V to +5.5V and supports data rates exceeding 400kHz. The device features rise time accelerators, hot swap capability, and logic level shifting for mixed-voltage applications. It provides ±6kV Class 3 HBM ESD protection on all pins and ±12kV on SDA/SCL lines. Typical supply current is 2.2µA, with shutdown current at 0.5µA. It is housed in an 8-lead MSOP package (3.0mm x 3.0mm) with a 0.7mm pitch, rated for -40°C to +85°C.

Signal Buffers, Repeaters, Splitters Feature Summary

• Dual-channel bidirectional buffering extends bus capacitance beyond the standard 400pF limit.
• Integrated rise time accelerator circuit reduces passive pull-up resistor power consumption while enhancing data rate performance.
• Hot swap protection prevents damage to data and clock lines during insertion into live backplanes.
• Logic level shifting enables operation in mixed power supply voltage environments.

Signal Buffers, Repeaters, Splitters Applications

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

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'IUZ' corresponds to the MSOP-8 package variant when sourcing. Confirm RoHS compliance status and lead-free finish specifications against the latest manufacturer datasheet. Ensure the operating temperature range meets system requirements of -40°C to +85°C. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component for systems requiring I2C bus extension beyond standard capacitance limits or those needing hot swap functionality. The dual-channel architecture suits applications isolating distinct bus segments. Verify that the required supply voltage falls between 2.3V and 5.5V. Consider the MSOP-8 footprint constraints during PCB layout design.

Signal Buffers, Repeaters, Splitters Part Context

The ISL33002 belongs to the ISL3300x family of I2C bus buffers from Renesas. This series includes single-channel (ISL33001) and quad-channel (ISL33003) variants. All members share core features like rise time acceleration and hot swap protection, differing primarily in channel count and pin configuration.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Direct substitutes include ISL33001IRT2Z for single-channel needs and ISL33003IRT2Z for quad-channel requirements. Verify pin compatibility and package dimensions before substitution. Check if alternative manufacturers offer functionally equivalent I2C buffers with similar ESD ratings and voltage ranges.
