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
IHD
).
Guaranteed, but not tested.
