DESCRIPTION
The PCA9545 is a quad bi-directional translating switch controlled
via the I2C bus. The SCL/SDA upstream pair fans out to four
downstream pairs, or channels. Any individual SCx/SDx channel or
combination of channels can be selected, determined by the
contents of the programmable control register. Four interrupt inputs,
INT0 to INT3, one for each of the downstream pairs, are provided.
One interrupt output, INT, acts as an AND of the four interrupt
inputs.
An active-LOW reset input allows the PCA9545 to recover from a
situation where one of the downstream I2C buses is stuck in a LOW
state. Pulling the RESET pin LOW resets the I2C state machine and
causes all the channels to be deselected as does the internal power
on reset function.
The pass gates of the switches are constructed such that the VDD
pin can be used to limit the maximum high voltage which will be
passed by the PCA9545. This allows the use of different bus
voltages on each pair, so that 1.8 V or 2.5 V or 3.3 V parts can
communicate with 5 V parts 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 5 V tolerant.
