Absolute Maximum Ratings(Note 1)

(Note 2)

Recommended Operating

Conditions

Note 1: Maximum Ratings are those values beyond which damage 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.
