ISL33001IUZ-T

Signal Buffers, Repeaters, Splitters Overview

The ISL33001IUZ-T is a single-channel I2C bus buffer manufactured by Renesas Electronics. It operates within a supply voltage range of +2.3V to +5.5V and supports an operating temperature range from -40°C to +85°C. The device is housed in an 8-lead MSOP package with SMD/SMT mounting style. It functions as a signal buffer and repeater, designed to extend bus capacitance beyond the standard 400pF limit while providing logic level translation for mixed-voltage applications.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides necessary buffering to extend I2C bus capacitance beyond the 400pF specification limit.
• Includes rise time accelerator circuitry to reduce passive pull-up resistor power consumption and improve data rate performance.
• Features hot-swap capability to prevent damage to data and clock lines during insertion into live backplanes.
• Supports logic level translation for mixed power voltage applications.

Signal Buffers, Repeaters, Splitters Applications

• I2C bus expansion and capacitance buffering
• Server racks in telecommunications, data communication, and computer servers
• Desktop computers
• Hot-swap circuit board insertion and bus isolation

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the manufacturer part number ISL33001IUZ-T against official Renesas documentation to ensure authenticity. Confirm that the component matches the specified MSOP-8 package and industrial temperature range. Check RoHS compliance status through authorized distributors. Validate the specific suffix 'T' indicates the correct tape and reel packaging configuration required for automated assembly processes.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when a single-channel I2C buffer is required to isolate sections of a bus or extend capacitance limits. Ensure the design requires operation between 2.3V and 5.5V. Consider the MSOP-8 footprint constraints. Verify if the integrated rise time accelerator and hot-swap protection align with the system's thermal and insertion requirements compared to basic buffers.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the ISL3300x series of I2C bus buffers, which also includes dual-channel variants like the ISL33002. These devices are categorized under interface ICs, specifically signal buffers and repeaters. The series is designed to address common I2C limitations regarding capacitance and speed in complex embedded systems.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The ISL33002 serves as a functional alternative for designs requiring dual-channel buffering instead of single-channel. Both parts share similar electrical characteristics, including the 2.3V to 5.5V supply range and hot-swap capabilities. Verify pinout compatibility if substituting directly on existing PCB layouts.
