1. The maximum operating output voltage (V_O(max)) is 6.0 V.
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.
