LTC4314CUDC

Signal Buffers, Repeaters, Splitters Overview

The LTC4314CUDC is a hot-swappable, four-channel, two-wire bus multiplexer manufactured by Analog Devices Inc. It allows a single upstream I2C or SMBus interface to connect to any combination of downstream buses or channels. The device features pin-selectable slave addresses and built-in bus buffering to isolate faults. Designed for robust operation in systems requiring multiple I2C peripherals, it supports hot insertion without disrupting the upstream host controller.

Signal Buffers, Repeaters, Splitters Feature Summary

• Pin-selectable addressing for flexible system integration
• Hot-swappable capability allowing connection without system reset
• Bus buffering isolates downstream faults from the upstream host

Signal Buffers, Repeaters, Splitters Applications

• I2C/SMBus peripheral expansion in embedded systems
• Hot-pluggable sensor array management
• Fault isolation in multi-node communication networks

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'CUDC' against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with the target I2C voltage levels and check for updated revision notes regarding electrical characteristics before finalizing procurement specifications.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when a single master needs to manage multiple I2C slaves across separate domains. Verify that the downstream devices comply with standard I2C timing requirements. Consider the maximum number of channels required and ensure the pin-selectable address options align with the system's addressing scheme to avoid conflicts.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the LTC4314 family of bus multiplexers. It is distinct from general-purpose switches as it specifically handles two-wire serial protocols. The 'C' typically denotes commercial temperature range, while 'UDC' indicates the specific package configuration, such as a small outline package.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Verify that substitute parts support the same hot-swap capabilities and bus buffering features. Ensure the replacement maintains identical addressing logic and electrical specifications for seamless integration.
