NOTES:
3. Not more than one output should be shorted at one time. Test duration should not exceed 100ms.
4. Inputs that are not measured are at VCC or GND.
5. FCT Input Loading: All inputs are 1 unit load. Unit load is ∆I_CC limit specified in Static Characteristics Chart, e.g., 1.6mA Max. @ 70^oC.
