6 / 6 page December 1990 6 Philips Semiconductors Product specification Dual 4-input NAND gate 74HC/HCT20 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. AC CHARACTERISTICS FOR 74HCT GND = 0 V; tr =tf = 6 ns; CL =50pF AC WAVEFORMS PACKAGE OUTLINES See “74HC/HCT/HCU/HCMOS Logic Package Outlines”.
