The soviet integrated circuit designation is an industrial specification for encoding the names of integrated circuits manufactured in the Soviet Union and the Post-Soviet states. 25 years after the dissolution of the Soviet Union, a number of manufacturers in Russia, Belarus, Ukraine, Latvia, and Uzbekistan still use this designation.
The designation uses the Cyrillic alphabet which sometimes leads to confusion where a Cyrillic letter has the same appearance as a Latin letter but is romanized as a different letter. Furthermore, for some Cyrillic letters the Romanization is ambiguous.
