Not more than one output should be shorted at a time, and the duration of the short circuit should not exceed one second.
NOTES:
2. ICCH is measured after applying a momentary ground, then 4.5 V, to the clock input with all data inputs at 4.5 V and the enable input
at GND.
3. ICCL is measured after applying a momentary ground, then 4.5 V, to the clock input with all data and enable inputs at GND.
