† _{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.}
§ _{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.}
