7 / 9 page December 1990 7 Philips Semiconductors Product specification 4-bit parallel access shift register 74HC/HCT195 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.
