- Q2654996 abstract "The 4000 series is a family of industry-standard integrated circuits (ICs) which implement a variety of logic functions using Complementary Metal–Oxide–Semiconductor (CMOS) technology, which were introduced in 1968 and are still in use today. Almost all IC manufacturers active during the era fabricated chips from this series. RCA sometimes advertised the line as COSMOS, standing for COmplementary Symmetry Metal-Oxide Semiconductor. The naming system followed the RCA convention of CA for analog, CD for digital, but did not relate to the Texas Instruments SN7400 series numbering scheme.4000 series parts have the advantage of lower power consumption, wider range of supply voltages (3 V to 15 V), and simpler circuit design due to the vastly increased fanout. However their slower speed (initially about 1 MHz operation, compared with bipolar TTL's 10 MHz) limits their applications to static or low-speed designs. New fabrication technology has largely overcome the speed problems, while retaining backward compatibility with most circuit designs. Although all semiconductors can be damaged by electrostatic discharge, the high impedance of CMOS inputs makes them more susceptible than bipolar transistor-based TTL devices. Eventually, the advantages of CMOS (especially the later 74HC series) phased out the older TTL chips, but at the same time ever increasing LSI techniques phased out the modular chip approach to design. The 4000 series also contains many chips with a considerably higher level of integration than most basic logic chips, including fully integrated 7-segment display counters, walking ring counters, and full adders.".
