A feature that is supported by all I2C switches by TI is Hot Insertion. The I2C switches can be added into a system without connecting any of the downstream channels during power up. For example, the 8-channel TCA9548A will not connect pins SD/SC[0–7] when hot inserting the device until explicitly commanded to by the I2C master. This means that when the TCA9548A is inserted into an active bus, it will not connect any of the channels, eliminating the chance of a device on those channels interfering with the main SDA/SCL line since the I2C master will have to command the TCA9548A to connect the SD2 and SC2 lines.
