* On products compliant to MIL-PRF-38535, this parameter does not apply.
All typical values are at VCC = 5 V.
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.
