6 / 7 page December 1990 6 Philips Semiconductors Product specification Octal buffer/line driver; 3-state; inverting 74HC/HCT240 DC CHARACTERISTICS FOR 74HCT For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”. Output capability: bus driver IICC 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.
