Not more than one output should be tested at a time, and the duration of the test should not exceed 10 ms.
For I/O ports, the parameter IOZ includes the input leakage current II.
§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.
