(1) This parameter will not be tested but assured by design
(2) Short circuit between two digital outputs (one in high the other in low state) will lead to the defined result "LOW"
(3) Measured chip, bond wires not included
(4) Measured on Power SO-36 devices
(5) Digital filtered with external clock, only functional test
