PCA9518 Datasheet (Texas Instruments) - Expandable Five-Channel I2C HUB

PCA9518, Expandable Five-Channel I2C HUB

The PCA9518 is an expandable five-channel bidirectional buffer for I2C and SMBus applications.

The I2C protocol requires a maximum bus capacitance of 400 pF, which is derived from the number of devices on the I2C bus and the bus length.

The PCA9518 overcomes this restriction by separating and buffer
