DC Electrical Characteristics
Note 7:
Max number of outputs defined as (n). n
1 data inputs are driven 0V to 3V. One output at LOW. Guaranteed, but not tested.
Note 8:
Max number of outputs defined as (n). n
1 data inputs are driven 0V to 3V. One output HIGH. Guaranteed, but not tested.
Note 9:
Max number of data inputs (n) switching. n
1 inputs switching 0V to 3V. Input-under-test switching: 3V to threshold (V
ILD
), 0V to threshold (V
