PI4MSD5V9543A - DIODES

PI4MSD5V9543A 2-Channel I2C Bus Switch

contents of the programmable control register. Two upstream pair fans out to two downstream pairs, or the 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 PI4MSD5V9543A to recover from a situation.
