* On products compliant to MIL-PRF-38535, this parameter does not apply.
All typical values are at VCC = 5 V.
This data-sheet limit may vary among suppliers.
§ Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
This is the increase in supply current for each input that is at the specified TTL voltage level, rather than VCC or GND.
