PCA9549 Datasheet (NXP Semiconductors)

PCA9549, Octal bus switch

The PCA9549 provides eight bits of high speed TTL-compatible 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 combination of channels can be selected via the I2C-bus, dete
