. It had a supply voltage range of 5V to 20V, which is much wider than any contemporary logic family. Almost all IC manufacturers active during this initial era fabricated models for this series. Its naming convention is still in use today.

History

The 4000 series was introduced as the ''CD4000 COS/MOS'' series in 1968 by

as a lower power and more versatile alternative to the

7400 series The 7400 series of integrated circuits (ICs) are a popular logic family of transistor–transistor logic (TTL) logic chips. In 1964, Texas Instruments introduced the SN5400 series of logic chips, in a ceramic semiconductor package. A lo ...

of transistor-transistor logic (TTL) chips. The logic functions were implemented with the newly introduced Complementary Metal–Oxide–Semiconductor (CMOS) technology. While initially marketed with "COS/MOS" labeling by RCA (which stood for Complementary Symmetry Metal-Oxide Semiconductor), the shorter ''CMOS'' terminology emerged as the industry preference to refer to the technology. The first chips in the series were designed by a group led by

Albert Medwin Albert H. Medwin (October 27, 1925 – October 26, 2020) was an American electrical engineer. He held several US patents, including ones in the field of electronic encoders. Medwin was involved in the early development of integrated circuits while ...

. Wide adoption was initially hindered by the comparatively lower speeds of the designs compared to TTL based designs. Speed limitations were eventually overcome with newer fabrication methods (such as self aligned gates of polysilicon instead of metal). These CMOS variants performed ona par with contemporary TTL. The series was extended in the late 1970s and 1980s with new models that were given 45xx and 45xxx designations, but are usually still regarded by engineers as part of the 4000 series. In the 1990s, some manufacturers (e.g.

) ported the 4000 series to newer HCMOS based designs to provide greater speeds.

Design considerations

. This makes the series ideal for use in prototyping LSI designs. While

ICs are similarly modular, these usually lack the symmetrical drive strength of CMOS and may therefore require more consideration of the loads applied on its outputs. Just like with TTL, buffered models can drive higher electrical current (mainly available for I/O-devices like octal latches and three-state drivers) but have a slightly higher risk of introducing ringing (transient oscillations) unless correctly damped or terminated.Lancaster, Don. ''CMOS Cookbook'', Many models contain a high level of integration, including fully integrated 7-segment display counters, walking ring counters, and full adders.
