* On products compliant to MIL-PRF-38535, this parameter does not apply.
†
All typical values are at V
CC
= 5 V.
‡
This parameter is characterized, but not production tested.
§
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 V
CC
or GND.
