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