ISL33001IUZ

Signal Buffers, Repeaters, Splitters Overview

The ISL33001IUZ 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 surface mount installation. Key electrical parameters include a typical static current of 2.1mA and a low shutdown current of 0.5μA. It provides ESD protection ratings of ±6kV Class 3 HBM on all pins, with specific ±12kV HBM protection on the SDA and SCL pins.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the manufacturer part number ISL33001IUZ against official Renesas documentation to confirm the MSOP-8 package and industrial temperature grade. Ensure compatibility with the required I2C interface specifications and voltage levels before procurement. Cross-reference datasheet revisions to validate pinout and electrical characteristics.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when a single-channel I2C buffer is required for systems needing extended bus capacitance or hot swap functionality. Consider the MSOP-8 footprint constraints and the +2.3V to +5.5V supply range. Evaluate if the single-channel configuration meets the system's signal routing needs compared to multi-channel alternatives.

Signal Buffers, Repeaters, Splitters Part Context

This component belongs to the ISL3300x series of I2C bus buffers, which also includes dual-channel (ISL33002) and quad-channel (ISL33003) variants. The series is designed to address common I2C limitations regarding capacitance and speed while providing robust protection features for embedded systems and peripheral interfaces.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Direct substitutes within the same family include the ISL33002 and ISL33003, though these offer different channel counts. Verify pin-to-pin compatibility and functional equivalence with other I2C buffer ICs from Renesas or third-party manufacturers if channel count differences are acceptable.
