ISOW7821: Side-2 Output State

Part Number: ISOW7821

Hi team,

When EN1 is Low, is the output of Side2 High-Z?

The data sheet only lists the output of Side1.

Best Regards,

    Hi Kobayashi-san,

    Thanks for reaching out.

    EN1 is on the Side1 of die and can only control the outputs that are on Side1. For ISOW7821, only OUTB is on Side1 and hence, EN1 can only enable or disable OUTB. There is no EN pin function provided on Side2 and hence, OUTA can't be disabled. It is always enabled.

    Let me know if there is any other question, thanks.
