TCA9511A - Hot Swappable I2C Bus and SMBus Buffer

The TCA9511A is a hot-swappable I2C bus buffer that supports I/O card insertion into a live backplane without corruption of the data and clock lines.

Control circuitry prevents the backplane-side I2C lines (in) from being connected to the card-side I2C lines (out) until a stop command or bus idle c
