Absolute Maximum Ratings(Note 2)
(Note 3) Recommended Operating
Conditions
Note 2: Absolute M aximum Ra tings are those valu es beyond w hich dam-
age to the device may occur.
Note 3: Unles s ot herwise specified all v olt ages are referenc ed to ground.
Note 4: Power Dis sipation te mperature d erating — pl astic “N” pa ckage: −
12 mW/°C from 65°C to 85°C.
DC Electrical Characteristics (Note 5)
Note 5: For a p owe r su pp ly o f 5V ± 10% the worst case output voltages (VOH, and VOL) occu r for HC at 4.5V. Thus the 4.5V valu es sho uld 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 3.85 V.) The w ors t c as e leak age cur-
rent (IIN, ICC, and IOZ) occur fo r C M OS at the h igher volta ge and so th e 6. 0V values s hould be used.
