4 / 8 page www.fairchildsemi.com 4 DC Electrical Characteristics (SOIC Package) Note 5: 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 6: Max number of outputs defined as (n). n − 1 data inputs are driven 0V to 3V. One output HIGH. Guaranteed, but not tested. Note 7: 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 (VIHD). Guaranteed, but not tested.
