• Supports 2-Wire Bus output interface

Signal Buffers, Repeaters, Splitters Applications

• I2C bus signal buffering
• Level translation between different voltage domains
• Hot swap applications requiring signal integrity

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix ',118' matches the required tape and reel packaging configuration. Confirm that the RoHS compliant status aligns with current environmental regulations for your region. Ensure the ECCN classification EAR99 meets export control requirements for your intended destination. Cross-reference the 8-TSSOP package dimensions against your PCB footprint design to guarantee mechanical compatibility during assembly.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when dual supply operation and hot swappable capabilities are required for I2C bus systems. Consider the 400kHz data rate limit and 5.2 pF input capacitance for high-speed signal integrity needs. Evaluate the open drain output structure against system pull-up requirements. Compare the 100 mW power dissipation rating against thermal constraints in the target application environment.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the family of signal buffers, repeaters, and splitters designed for I2C and SMBus interfaces. It complements similar devices like the PCA9509DP, which offers level translation without the hot swappable feature. These components address signal degradation and voltage mismatch issues in complex multi-voltage electronic systems.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PCA9509DP is a related level translating I2C-bus/SMBus repeater but lacks the hot swappable specification. Verify functional equivalence regarding voltage ranges and data rates before substitution.
