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