* 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.
§ The parameters IOZH and IOZL include the input leakage current.
This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
