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, TA = 25°C and VCC = 5V.

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

Note 4: TA = 25°C and VCC = 5V.

Electrical Characteristics

over recommended operating free air temperature range (unless otherwise noted)

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: With all outputs open, inputs A through D grounded, and 4.5V applied to S0, S1, CLEAR, and the serial inputs, ICC is tested with momentary ground,

then 4.5V applied to CLOCK.
