(1) All typical values are at V
CC
= 5 V.
(2) On products compliant to MIL-PRF-38535, this parameter does not apply.
(3) On products compliant to MIL-PRF-38535, this parameter is not production tested.
(4) Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
(5) This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
CC
or GND.
