DC CHARACTERISTICS FOR 74HCT

For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”.

Output capability: standard

ICC category: SSI

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.
