Absolute Maximum Ratings(Note 1)
(Note 2)
Recommended Operating
Conditions
Note 1: Absolute Maximum Ratings are those values beyond which dam-
age to the device may occur.
Note 2: Unless otherwise specified all voltages are referenced to ground.
Note 3: Power Dissipation temperature derating — plastic “N” package:
12 mW/
qC from 65qC to 85qC.
DC Electrical Characteristics (Note 4)
Note 4: For a power supply of 5V
r10% 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, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used.
