Note 10: All typicals are at VCC = 5V, TA = 25°C.
Note 11: Not more than one output should be shorted at a time, and the duration should not exceed one second.
Note 12: ICCH is measured with the load HIGH, then again with the load LOW, with all other inputs HIGH and all outputs OPEN.
Note 13: ICCL is measured with the clock input HIGH, then again with the clock input LOW, with all other inputs LOW and all outputs OPEN.
