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: C L = 15 pF , RL = 2 kΩ , TA = 25°C and VCC = 5V Note 3: C L = 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, clock inhibit and shift/load at 4.5V, and a clock pulse applied to the CLOCK input, ICC is measured first with the parallel inputs at 4.5V, then again grounded.
