Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

3. For a power supply of 5 V

±10% the worst−case output voltages (VOH, and VOL) occur for HC at 4.5 V. Thus the 4.5 V values should be used

when designing with this supply. Worst−case VIH and VIL occur at VCC = 5.5 V and 4.5 V respectively. (The VIH value at 5.5 V is 3.85 V.)

The worst−case leakage current (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0 V values should be used.
