This standard will be useful to users, manufacturers, educators, technical writers, and others interested in the characterization, nomenclature, and classification of microelectronics devices. There are general guidelines for both letter symbols and abbreviations applicable to all integrated circuits, and detailed sections for digital ICs, linear (analog) ICs, interface ICs (including D/A and A/D converters), voltage regulators, charge-transfer devices. The standard lists and defines more than 400 of the most common physical and electrical terms applicable to these devices and shows the industry-standard symbol and abbreviations that have been established for such terms.
