Note 4: For a power supply of 5V ±10% the worst case output voltages (VOH and VOL) occur for HC at 4.5V. Thus the 4.5V values should be used when
designing with this supply. Worst case VIH and VIL occur at VCC = 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage cur-
rent (IIN, ICC, IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used.
