74HC/HCT594
DC CHARACTERISTICS FOR
74HCT
For the DC characteristics, see
“74HC/HCT/HCU/HCMOS Logic
Family Specifications”.
Output capability: parallel outputs,
bus driver; serial output, standard.
ICC category: MSI.
Note to HCT types
The value of additional quiescent
supply current (∆ICC) for a unit load of
1 is given in the family specifications.
To determine ∆ICC per input, multiply
this value by the unit load coefficient
shown in the following table.
