Note 1: Not more than one output should be shorted at a time, and the duration should not exceed one second.
Note 2: ICCH is measured with the load high, then again with the load low, with all other inputs high and all outputs
open.
Note 3: ICCL is measured with the clock input high, then again with the clock input low, with all other inputs low
and all outputs open.
