DC CHARACTERISTICS FOR 74HCT
For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”.
Output capability: 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 table below.
