(1) On products compliant to MIL-PRF-38535, this parameter is not production tested at V_CC = 0 V.

(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 at one of the specified TTL voltage levels, rather than 0 V or V_CC.
