(1) For test conditions shown as MIN, MAX, or TYP, use the appropriate value specified in the recommended operating conditions table.
(2) I_I applies to input-only pins and bi-directional pins. For input-only pins, I_I indicates the input leakage current. For bi-directional pins, I_I
includes input leakage current and off-state (hi-Z) output leakage current.
(3) I_OZ applies to output-only pins, indicating off-state (hi-Z) output leakage current.
