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 V_CC or GND.
5. FCT Input Loading: All inputs are 1 unit load. Unit load is ∆I_CC limit specified in Electrical Specifications table, e.g., 1.6mA Max. at 70^oC.
