## Why It Matters
The 164 series integrated circuits represent an important development in Soviet electronics during the 1970s, providing a domestic alternative to Western CMOS logic families. By developing a series equivalent to the 4000 series but with a different physical package (flatpack metal), the Soviet Union could leverage existing design knowledge while adapting to local manufacturing capabilities. This helped standardize electronic components across Soviet industry and reduced dependence on foreign technology. The series played a role in the broader Soviet effort to develop domestic semiconductor technology and contributed to the advancement of digital electronics in the Soviet Union during that period.

## Notable For
- It was the first Soviet CMOS logic series packaged in a flatpack metal package.
- The series maintained functional compatibility with the 4000 series while using Soviet manufacturing standards.
- It was manufactured by the Novosibirsk Semiconductor Plant, a key Soviet electronics manufacturer.
- The flatpack metal packaging provided better thermal performance and protection compared to other packaging options available at the time.
- The 164 series helped standardize electronic components across Soviet industry and supported the development of digital systems in the Soviet Union.

## Body
### Technical Specifications
The 164 series integrated circuits are CMOS logic devices that were designed as a Soviet equivalent to the 4000 series. They share the same functional specifications but differ in physical packaging. The flatpack metal package used for the 164 series provided better thermal dissipation and environmental protection compared to other packaging options available at the time.

### Development Timeline
The development of the 164 series began in 1972 as research and development work. By 1974, the series had progressed to industrial manufacturing, indicating successful transition from prototype to production. This timeline shows the typical development cycle for Soviet electronics during the 1970s.

### Manufacturing and Standards
Manufactured by the Novosibirsk Semiconductor Plant, the 164 series complies with Soviet integrated circuit designation standards. This meant the components followed specific naming conventions and technical specifications established by Soviet authorities for electronic components. The plant was one of the major semiconductor manufacturers in the Soviet Union, contributing to the country's electronics industry.

### Packaging Technology
The flatpack metal package used for the 164 series was a significant advancement in Soviet packaging technology. This type of packaging was chosen for its superior thermal performance and protection against environmental factors compared to plastic packages. The metal casing provided better shielding against electromagnetic interference and offered improved durability in industrial applications.

### Technical Classification
As a CMOS integrated circuit series, the 164 series operates using complementary metal-oxide-semiconductor technology, which is known for low power consumption and high noise immunity. The series is classified as an integrated circuit series, sharing the same part prefix and functional characteristics as other members of the 164 family. This classification helps in identifying and using the components in electronic designs.
