TCA4311ADGKR TI Signal Buffers, Repeaters, Splitters

TCA4311ADGKR is an I²C bus buffer and voltage level shifter from Texas Instruments, packaged in 8-VSSOP, for mixed-voltage I²C bus systems. It realizes bidirectional voltage translation between 1.2V and 5.5V without extra direction control signals, supporting standard 100kHz and fast 400kHz I²C bus communication speeds. It features low on-resistance and minimal crosstalk between channels, and supports hot-swap operation for live circuit maintenance. Integrated ESD protection enhances anti-interference capability, with operating temperature covering -40°C to 85°C. For mixed-voltage boards needing I²C signal conversion and buffering, choose this compact device. Typical applications include battery-powered portable devices, industrial sensor networks, consumer electronics and mixed-voltage embedded control systems.
