Notes:
15. These parameters are measured from the input signal changing, until the output pin goes to a high-impedance state.
16. CY7C142/CY7C146 only.
17. A write operation on Port A, where Port A has priority, leaves the data on Port B’s outputs undisturbed until one access time after one of the following:
18. 52-pin PLCC and PQFP versions only.
