The TCA9511ADGKR from Texas Instruments is a hot-swappable I2C bus buffer designed to support I/O card insertion into a live backplane without corrupting data and clock lines. It provides bidirectional buffering, isolating backplane and card capacitances.
This buffer operates across a wide supply voltage range of 2.3V to 5.5V and supports I2C/SMBus protocols at frequencies up to 400kHz. Key features include an enable pin and hot-swap capability, with pre-charge circuitry on SDA and SCL lines to minimize current during live insertion.
The device is rated for an operating temperature range of -40°C to 125°C (TA). It is available in an 8-VSSOP package and is suitable for applications requiring robust I2C communication during hot-swap events.
Mounting is via surface mount technology. The TCA9511ADGKR is designed to accommodate standard mode and fast mode I2C devices, supporting clock stretching, arbitration, and synchronization.
