PI4MSD5V9545A Overview
Channel selection via I2C bus Power-up with all multiplexer channels deselected Capacitance isolation when channel disabled No glitch on power-up Supports hot insertion 5 V tolerant inputs 0 Hz to 400 kHz clock frequency ESD protection exceeds 8000 V HBM per JESD22- Any individual SCx/SDx channel or bination of channels can be selected, determined by the contents of the programmable control register. Four interrupt inputs, INT0 to INT3, one for each of the downstream pairs, are provided. One interrupt output, INT, acts as an AND of the four interrupt inputs.
