PCA9616 3-Channel Buffer

NXP Semiconductor PCA9616 3-Channel Multipoint Differential I²C-bus Buffer is a Fast-mode Plus (Fm+) SMBus/I²C-bus buffer that extends the normal single-ended SMBus/I²C-bus through electrically noisy environments using a differential SMBus/I²C-bus (dI²C) physical layer, which is transparent to the SMBus/I²C-bus protocol layer. PCA9616 consists of three single-ended to differential driver channels for the SCL (serial clock), SDA (serial data), and a third channel useful for INT or another signaling. Additional circuitry allows the NXP PCA9616 to be used for 'hot swap' applications, where systems are always on but require insertion or removal of modules or cards without disruption to existing signals. The dI²C-bus buffers are ideally suited for rugged high noise environments and/or longer cable applications, allow multiple slaves, and operate at bus speeds up to 1MHz clock rate.
