Description

The PCA9544APW is a quad bidirectional Translating Switch controlled via the I²C bus. The SCL/SDA upstream pair fans out to four downstream pairs or channels. One SCL/SDA pair can be selected at a time and this is determined by the contents of the programmable control register. Four interrupt inputs (INT3\\-INT0\\), one for each of the downstream pairs, are provided. One interrupt output (INT\\) acts as an AND of the four interrupt inputs. A power-ON reset function puts the registers in their default state and initializes the I²C state machine, with no channel selected. 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 PCA9544A. External pull-up resistors pull the bus up to the desired voltage level for each channel.
