* 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.
§
The parameters I
OZH
and I
OZL
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 limit may vary among suppliers.
||
This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
CC
or GND.
