The DIODES™ PI4MSD5V9548A is an octal bidirectional
translating switch controlled via the I2C bus. The SCL/SDA
upstream pair fans out to eight 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.
An active LOW reset input allows the PI4MSD5V9548A to
recover from a situation where one of the downstream buses is
stuck in a LOW state. Pulling the RESET pin LOW resets the
I2C bus 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
VCC pin can be used to limit the maximum high voltage
which will be passed by the PI4MSD5V9548A. This allows the
use of different bus voltages on each pair, so that 1.2V, 1.8V or
2.5V or 3.3V 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.
