NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value under the recommended operating conditions for the applicable type.
2. All typical values are at V_CC = 5V, T_amb = 25°C.
3. Not more than one output should be shorted at a time. For testing I_OS, 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 should be performed last.
