1) Hysteresis is implemented to avoid metastable states and switching due to internal ground bounce. It can't be guaranteed
that it suppresses switching due to external system noise.
2) For currents smaller than the I_OL/OH from the test condition the defined Max. value stays unchanged.
3) Rise / fall times are defined 10% - 90% of V_EXT/FLEX.
4) V_IHx = 0.27 * V_EXT/FLEX + 0.545V
5) V_ILx = 0.17 * V_EXT/FLEX
6) The values are only valid if the pad is not used during operation, otherwise I_SC defines the limits for operation.
