11、SI 10-1999 Foreword The CENELEC Electronic Components Committee (CECC) is composed of those member countries of theEuropean Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of the System is
12、 to facilitate international trade by the harmonization of the specifications and quality 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 accepted by all membe
13、r countries without further testing. This specification has been formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmonized specifications for INTEGRATED ANALOGUE SWITCHING CIRCUITS. It should be read in conjunction with t
14、he current regulations for the CECC System. At the date of printing of this specification the member countries of the CECC are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the UnitedKingdom. Preface This blank
15、 detail specification (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 IEC147: Essential ratings and characteristics of semiconductor devices and general principles of measu
16、ring methods. The text of this BDS was circulated to the CECC for voting in the document indicated below and was ratified by the President of the CECC for printing is a CECC Specification. It is recognized that the layout proposed cannot apply to all detail specifications based on this document. For
17、 example when several similar devices are covered by the same detail specification, it may be convenient to give the limiting values in a table. Notice In accordance with the decision of the CECC Management Committee this specification is published initially in English and French. The German text wi
18、ll follow as soon as it has been prepared.
