6 / 7 page September 1993 6 Philips Semiconductors Product specification Dual 2-to-4 line decoder/demultiplexer 74HC/HCT139 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.
