Analog Devices, Inc. LTC4301CDDPBF is a hot swappable 2-wire bus buffer with bus hold circuitry that is part of the integrated circuits (ICs) category. It allows I2C and SMBus devices to be added or removed from a live backplane without corrupting the data and clock buses. Functions: 1. Hot swappable 2-wire bus buffer 2. Supports I2C and SMBus systems 3. Prevents corruption of data and clock buses during live insertions or removals of devices 4. Bus hold circuitry maintains last valid bus state during power-up and power-down Applications: 1. Telecommunication equipment 2. Networking equipment 3. Industrial automation systems 4. Consumer electronics 5. Server systems Alternative Components: 1. Texas Instruments TCA4311A 2. Maxim Integrated DS28E17 3. ON Semiconductor NCS36510 Embedded Modules: 1. Address Translation: Allows multiple devices with the same address to be connected without conflict. 2. Hot Swapping Circuitry: Safely inserts and removes devices from the bus without disruption. 3. Bus Hold Function: Maintains the last valid bus state during power transitions. --- Q&A: 1.
