A common use ofthe'AC/'ACT158isthemoving ofdatafrom two groupsofregisterstofourcommon output busses.The particularregisterfromwhichthedatacomes isdeterminedby thestateoftheSelectinput.A less obvioususe isas a functiongenerator.The 'AC/'ACT158can generatefourfunctionsoftwo variableswithone variablecommon.
