Prehľad produktu

The PCA9543APW,112 is a 2-channel I²C-bus Switch with interrupt logic and reset controlled by the I²C-bus. The SCL/SDA upstream pair fans out to two downstream pairs or channels. Any individual SCx/SDx channels or combination of channels can be selected, determined by the contents of the programmable control register. Two interrupt inputs, INT0 and INT1, one for each of the downstream pairs, are provided. One interrupt output, INT, which acts as an AND of the two interrupt inputs, is provided. An active low reset input allows the switch 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-bus state machine and causes all the channels to be deselected, as does the Internal power-ON reset function.
  • 2 Active low interrupt inputs
  • Active low interrupt output

  • 2 Address pins allowing up to 4 devices on the I²C-bus
  • Power-up with all switch channels deselected
