3. With the outputs open, clock inhibit and shiftlloau at 4.bV, and a clock pulse applied to the clock input.
lee is measured first with the parallel inputs at 4.5V, then with the parallel inputs grounded.
, All typical values are at Vee = 5V, T A = 25° e.
2 For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions
for the applicable device type.
3 Not more than one output should be shorted at a time.
