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. 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  
OS  
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 tests should be performed last.
