5 / 9 page 5 www.fairchildsemi.com 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 (V ILD). AC Electrical Characteristics Note 9: Voltage Range 5.0 is 5.0V ± 0.5V. AC Operating Requirements Note 10: Voltage Range 5.0 is 5.0V ± 0.5V.
