DC Electrical Characteristics (Continued)
Note 6: Maximum number of outputs that can switch simultaneously is n. (n − 1) outputs are switched LOW and one output held LOW.
Note 7: Maximum number of outputs that can switch simultaneously is n. (n − 1) outputs are switched HIGH and one output held HIGH.
Note 8: Maximum number of data inputs (n) switching. (n − 1) inputs switching 0V to 3V (ACTQ). Input under test switching 3V to threshold (VILD).
