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 VCC = 5V, TA = 25_C.
3. IOH2 is transient current necessary to guarantee a Low to High transition in a 70W transmission line.
4. IOL2 is transient current necessary to guarantee a High to Low transition in a 70W transmission line.
5. Not more than one output should be shorted at a time. For testing IOS, 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, IOS tests should be performed last.
