Notes:
(1) VIL min and VIH max are reference values only and are not tested.
(2) This parameter is characterized initially and after a design or process change that affects the parameter. Not 100% tested.
(3) Each I/Os must be externally limited to a maximum of 25mA and each octal (I/O0.0 to I/O0.7 and I/O1.0 to I/O1.7) must be limited to a
maximum current of 100mA for a device total of 200mA.
(4) The total current sourced by all I/Os must be limited to 160mA.
