Note 8: All typicals are at VCC = 5V, TA = 25°C.
Note 9: Not more than one output should be shorted at a time, and the duration should not exceed one second.
Note 10: 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.
