PI6ULS5V9517BZEEX

Signal Buffers, Repeaters, Splitters Overview

The PI6ULS5V9517BZEEX is a level translating I2C bus/SMBus repeater manufactured by Diodes Incorporated. It operates with Port A supply voltage (VCCA) ranging from 0.8 V to 5.5 V and Port B supply voltage (VCCB) ranging from 2.2 V to 5.5 V. The device supports SMBus frequencies up to 400 kHz and features an active HIGH enable input. Electrical characteristics include a maximum propagation delay of 300 ns from Port B to Port A and 230 ns from Port A to Port B. Input/output capacitance is specified at 6 pF, and the component provides ESD protection rated at 8000 V in HBM mode. It is housed in an 8-pin TDFN package.

Signal Buffers, Repeaters, Splitters Feature Summary

• Supports bidirectional data translation between two independent I2C or SMBus buses operating at different voltage levels.
• Features an active HIGH enable pin that controls signal transmission between ports.
• Provides high electrostatic discharge protection for robust operation in sensitive environments.

Signal Buffers, Repeaters, Splitters Applications

• Interfacing low-voltage logic devices with standard voltage peripherals on I2C networks.
• Expanding I2C bus topologies using star or series configurations.
• Connecting mixed-voltage subsystems within embedded systems.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and tape/reel configuration. Confirm RoHS compliance status and lead-free manufacturing details directly with the manufacturer before procurement. Ensure the selected variant matches the required PCB land pattern specifications.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when interfacing buses with distinct voltage requirements, specifically where Port A requires support down to 0.8 V while Port B operates at 2.2 V or higher. Consider the 8-pin TDFN package dimensions for space-constrained designs. Evaluate the propagation delay limits to ensure they meet the timing constraints of the target communication protocol.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI6ULS5V9517B family of level translating repeaters. The ZEEX suffix indicates an 8-pin 2x3 mm TDFN package with Pb-free and Green manufacturing attributes. Other variants in the family utilize MSOP packages, offering alternative form factors for similar electrical functions.
