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