Philips Semiconductors Product specification
Triple 3-input AND gate 74HC/HCT11
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.
