File Size : 116 KB Manufacturer:UC Description:Other considerations are the Fanout and Loading tables. Some manufacturers relate these numbers in therms of 7400 gate loads … Philips Semiconductors feels that FAST is unlikely to be mixed with other logic families and so gives the loading factors in terms of FAST unit loads. A FAST unit load is defined to be 0.6mA in the Low state and 20µA in the High state. Thus in the case of the 74F00 gate, the inputs are specified as 1 Ful (FAST unit load) each … the outputs need a little explanation. The standard FAST output is specified with an IOL sink current of 20mA and an IOH of +1.0mA. Thus the fanout of this gate in the Low state is 20mA/0.6mA or 33 FAST unit loads. In the High state the fanout is 1mA/20µA or 50 FAST unit loads. In each case, the Fanout and Loading Table on the Philips data sheets states the High/Low fanout numbers … thus the 74F00 output fanout is specified as 50/33 Ful.
