TCA9511A Description
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 mand or bus idle condition occurs on the backplane without bus contention on the card. When the connection is made, this device provides...
