(1) Not more than one output should be tested at a time, and the duration of the test should not exceed 2 ms.
(2) For I/O ports, the parameter IOZ includes the input leakage current.
(3) This is the increase in supply current for each input that is at one of the specified TTL voltage levels, rather than 0 V or VCC.
