Notes
1. H = HIGH voltage level
h = HIGH voltage level one set-up time prior to the LOW-to-HIGH clock transition
L = LOW voltage level
I = LOW voltage level one set-up time prior to the LOW-to-HIGH clock transition
q, d = lower case letters indicate the state of the referenced input (or output) one set-up time prior to the
LOW-to-HIGH clock transition
X = don’t care
↑ = LOW-to-HIGH clock transition

DC CHARACTERISTICS FOR HCT
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.
