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