Absolute Maximum Ratings(Note 1)

Note 1: The “Absolute Maximum Ratings” are those values beyond which

the safety of the device cannot be guaranteed. The device should not be

operated at these limits. The parametric values defined in the Electrical

Characteristics tables are not guaranteed at the absolute maximum ratings.

The “Recommended Operating Conditions” table will define the conditions

for actual device operation.

Recommended Operating Conditions

Note 2: CL = 15 pF, RL = 2 kΩ, IA = 25°C and VCC = 5V.

Note 3: CL = 50 pF, RL = 2 kΩ, IA = 25°C and VCC = 5V.

Note 4: TA = 25°C and VCC = 5V.

DC Electrical Characteristics

Note 5: All typicals are at VCC = 5V, TA = 25°C.

Note 6: Not more than one output should be shorted at a time, and the duration should not exceed one second.

Note 7: ICC is measured with all outputs open, CLEAR and LOAD inputs grounded, and all other inputs at 4.5V.
