All typicals are at VCC e 5V TA e 25 C
Note 2
Not more than one output should be shorted at a time and the duration should not exceed one second
Note 3
ICCH is measured with the load high then again with the load low with all other inputs high and all outputs open
Note 4
ICCL is measured with the clock input high then again with the clock input low with all other inputs low and all outputs open
