NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2. All typical values are at V
= 5V, T
= 25 C.
3. I
OH2
is transient current necessary to guarantee a Low to High transition in a 70 transmission line.
4. I
is transient current necessary to guarantee a High to Low transition in a 70 transmission line.
5. Not more than one output should be shorted at a time. For testing I
, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged
shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In
any sequence of parameter tests, I
OS
tests should be performed last.
