All outputs high

VCC = max (Note 2)

All outputs low

VCC = max (Note 3)

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.
