Hi

What A1 and A2 pin when DIR is high happens? A1 and A2 will be low with internal pulldown?

The customer concern is that Hi-Z situation of Input pins when the input line opened.

Regards,

K

    Hi,

    There is no internal pull-down function at A1 and A2 when DIR is high. If DIR is high and input line is opened, it is at Hi-Z state for DC signal. But the output state is not determined when input is floating.

    Regards,
