1 General description

The PCA9848 is an ultra-low voltage, octal bidirectional translating switch controlled via the I2C-bus. The SCL/

SDA upstream pair fans out to eight downstream pairs, or channels. Any or all SCx/SDx channels can be

selected, determined by the programmable control register. This feature allows multiple devices with the same

I2C-bus address to reside on the same bus. The switch device can also separate a heavily loaded I2C-bus into

separate bus segments, eliminating the need for a bus buffer.

An active LOW reset input allows the PCA9848 to recover from a situation where one of the downstream I2Cbuses

is stuck in a LOW state. Pulling the RESET pin LOW resets the I2C-bus state machine and deselects all

the channels, as does the internal Power-On Reset (POR) function.

The pass gates of the switches are constructed such that the VDD1 pin is used to limit the maximum high voltage

which is passed by the PCA9848. This allows the use of different bus voltages on each channel, so that 0.8 V,

1.8 V, 2.5 V or 3.3 V parts can communicate without any additional protection. External pull-up resistors pull the

bus up to the desired voltage level for each channel. All I/O pins are 3.6 V tolerant.

2 Features and benefits
