This article describes the nomenclature for integrated circuits manufactured in the Soviet Union.
54LS32 Datasheet PDF –
The designation uses the Cyrillic alphabet which sometimes leads to confusion where a Cyrillic 54ls332 has the same appearance as a Latin letter but is romanized as a different letter. Furthermore, for some Cyrillic letters the Romanization is ambiguous. The nomenclature for integrated circuits has changed somewhat over the years as new standards were published:.
Throughout this article the standards are referred to by the year they came into force. Before each manufacturer used its own integrated circuit designation.
These were typically used in parallel with the standards. However, integrated circuits for military, aerospace, and nuclear applications in Russia still have to follow the standard designation. Underlining this, the standard is explicitly labelled a Russian military standard. Beside Russia the standard is applied in Belarus as 54ls3. Bulgarian designations for bipolar integrated circuits, e.
For the number after the functional group datashee is no concept of a series. Instead, that number usually matches the Western counterpart e. Also as a dataseet of dissolution of the Soviet UnionCOCOM restrictions were lifted and Russian integrated circuit design firms gained access to foundries abroad. In that sense it could be argued that the importance of the Soviet designation has spread across the globe. When foundries are not able to label the circuit in the Cyrillic alphabet then the Latin alphabet is used e.
In general, devices already in production when a new standard came out kept their old designation. 54sl32, in some case devices were renamed:. The package of an integrated circuit was generally not indicated in the designation, except:.
For bare chips without a package an additional datazheet indicates the constructive variant. For the and standards the variant digit follows immediately after the package designation N e. A manufacturer designation was introduced only datassheet the standard. The table below is incomplete, many manufacturers still do not use their assigned designation.
Manufacturer logos  are more common. Although not strictly part of the designation, a number of markings are often found on integrated circuit packages: For mask-programmed devices e. For bare chips a one digit constructive variant identifier follows the type designation. A date code is usually printed on the package. In the early s the date code consisted of a Roman numeral for the month and a two-digit year e.
Soviet integrated circuit designation
Later the month was given as one or two digits e. In the late s most plants switched to a 4-digit code with a 2-digit year followed by a 2-digit month e. Overall, the date code format was not strictly enforced. At least the series of integrated circuits bore an IEC letter and digit code e. A1 for January The Romanization of Russian is standardized, only there are at least 11 standards to choose from.
Fortunately, the Soviet integrated circuit designation uses datashdet subset of the Cyrillic alphabet where rather few letters are ambiguous:. It should be noted that the French romanization of Russian and the German romanization of Russian differ in some letters from the one used in English.
