(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 I_OZ 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 V_CC.
