Manufacturer: Diodes Incorporated

Overview: PI4MSD5V9543A 2 Channel I2C bus switch with interrupt logic and.

General Description

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.
