Logic Families. Introduction & Overview. CSET 4650 Field Programmable Logic Devices. Dan Solarek Logic Families Logic Family : A collection of different ICs that have similar circuit characteristics The circuit design of the basic gate of each logic family is the same The most important parameters for evaluating and comparing logic families include : Logic Levels Power Dissipation Propagation ... An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision of silicon and revision of document to which it applies.
