This specification specifies the terms, definitions, symbols, test methods and other material for monolithic integrated (micro)circuits (*), as defined in IEC 747, necessary to prepare appropriate detail sepcifications (DS) in the CECC System. Supplementary requirements for different families of integrated microcircuits are included in separate specifications. (*) In the following term "integrated circuits" is used.
