13、 of thosemember countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System forelectronic components of assessed quality. The object of the System is to facilitate international trade by the harmonization of the specifications and q
14、uality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby acceptable in all member countries without further testing. This specification has been formally approve
15、d by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmonized specifications for PROGRAMMABLE LOGIC ARRAYS (PLA). It should be read in conjunction with the current regulations for the CECC System. At the date of printing of this specificatio
16、n the member countries of the CECC are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, theNetherlands, Norway, Portugal, Spain, Sweden, Switzerland, and theUnitedKingdom, and copies of it can be obtained from the addresses shown on the blue fly-sheet. Preface This blank detail s
17、pecification (BDS) was prepared by CECC WG9 “Integrated circuits”. It is based, wherever possible, on the Publications of the International Electrotechnical Commission and in particular on IEC747: Semiconductor devices Discrete devices and integrated circuits. The text of this BDS was circulated to
18、the CECC for voting in the documents indicated below and was ratified by the President of the CECC for printing as a CECC specification. It is recognized that the layout proposed cannot be applied to all detail specifications based on this document. For instance, it may be preferable to indicate the
19、 limiting values in the form of a table when several similar devices appear in the same detail specification. In accordance with the decision of the CECC Management Committee this specification is published initially in English and French. The German text will follow as soon as it has been prepared.
