The LTC4305CGN#PBF is an IC component from Linear Technology (now part of Analog Devices Inc.), designed for I2C bus applications. It serves as a level translator and hot-swappable I2C bus buffer, providing various functionalities to enhance the I2C communication.
This IC component features a bidirectional I2C bus buffer that allows voltage level translation between two I2C buses with different voltage levels. It supports a wide range of supply voltages, from 1.65V to 5.5V, making it compatible with a wide range of I2C devices.
Key features of the LTC4305CGN#PBF include:
1. Level Translation: The IC translates I2C logic voltage levels between two buses with different voltage levels. This enables communication between devices operating on different voltage domains.
2. Hot-Swappable: The LTC4305CGN#PBF allows hot swapping of I2C devices without interrupting the bus. It features a built-in bidirectional current-limited bus switch, which prevents excessive current flow during hot swapping.
3. Stuck Bus Back-Up: In case of a stuck bus condition, where one I2C bus becomes stuck low, the LTC4305CGN#PBF detects this and isolates the faulty bus from the rest of the system, preventing it from interfering with other devices
