DC CHARACTERISTICS FOR 74HCT
For the DC characteristics see â74HC/HCT/HCU/HCMOS Logic Family Specificationsâ. Transfer characteristics are
given below.
Output capability: standard
ICC category: SSI
Notes to HCT types
The value of additional quiescent supply current (âICC) for a unit load of 1 is given in the family specifications.
To determine âICC per input, multiply this value by the unit load coefficient shown in the table below.
