PI6ULS5V9511AZWEX

Specialized Overview

The PI6ULS5V9511AZWEX is a bidirectional I2C hot-swappable buffer and repeater manufactured by Diodes Incorporated. It supports I/O card insertion into live backplanes without disrupting data or clock buses. The device features built-in rise time accelerators on SDA and SCL lines, pre-charging them to 1.1V to minimize charging current during insertion. Control circuits prevent backplane connection until a stop command or bus idle state occurs. It operates within a supply voltage range of 2.3V to 3.6V, with a maximum clock frequency of 400kHz and a supply current of 1.7mA. The component is housed in an 8-MSOP package.

Specialized Feature Summary

• Hot-swappable I2C/SMBus buffering for safe insertion into powered backplanes
• Control logic isolates the backplane until bus idle or stop condition detected
• Integrated rise time acceleration with 1.1V pre-charge capability

Specialized Applications

• I/O card insertion into live server backplanes
• I2C bus extension in hot-pluggable systems
• SMBus signal buffering in industrial equipment

Specialized Procurement Notes

Verify the complete part number including suffix AZWEX against official Diodes Incorporated documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage requirements of 2.3V to 3.6V. Confirm RoHS3 compliance status through current manufacturer declarations. Cross-reference datasheet revision dates to ensure alignment with design specifications.

Specialized Selection Notes

Select this component when hot-swappable I2C functionality is required with minimal bus disruption. The integrated rise time accelerator reduces stress on connected devices during insertion. Verify that the 8-MSOP package fits the PCB layout constraints. Ensure the application does not exceed the 400kHz maximum clock frequency specification.

Specialized Part Context

This part belongs to the PI6ULS5 series of I2C interface buffers from Diodes Incorporated. The series focuses on providing reliable signal integrity for hot-pluggable applications. Similar parts in the family may offer different channel counts or package options but share the core hot-swap protection and rise-time acceleration technologies.

Specialized Replacement Considerations

Check Diodes Incorporated cross-reference tools for direct replacements. Verify pinout compatibility if substituting with other I2C buffers. Ensure replacement parts support the same 2.3V-3.6V operating range and 400MHz speed.
