The PCA9549 provides eight bits of high speed TTL-patible bus switching controlled by the I2C-bus. The low ON-state resistance of the switch allows connections to be made with minimal propagation delay. Any individual A to B channel or bination of channels can be selected via the I2C-bus, determined by the contents of the programmable Control register.
