The TCA4307DGKR from Texas Instruments is a hot-swappable I2C bus and SMBus buffer designed to support I/O card insertion into a live backplane without corrupting data and clock lines. It provides bidirectional buffering and features stuck bus recovery with automatic bus recovery. The device operates over a wide power-supply voltage range of 2.3V to 5.5V and supports standard mode and fast mode I2C devices.
Key electrical characteristics include a maximum frequency of 0.4MHz and a typical quiescent current of 2.5mA. It supports clock stretching, arbitration, and synchronization, and its pins remain high-impedance when powered off. The operating temperature range is -40°C to 125°C (TA).
This buffer is available in an 8-VSSOP package and an 8-TSSOP, 8-MSOP package, both surface-mount types. Its general-purpose application makes it suitable for various system designs requiring robust I2C communication during hot-swapping events.
