Cmos Ic. The following is a list of cmos 4000 series digital logic integrated circuits. Due to the popularity of these parts other manufacturers released pin to pin compatible logic devices and kept the 4000 sequence number as an aid to identification of compatible parts.

Complementary metal oxide semiconductor cmos also known as complementary symmetry metal oxide semiconductor cos mos is a type of metal oxide semiconductor field effect transistor mosfet fabrication process that uses complementary and symmetrical pairs of p type and n type mosfets for logic functions. In fact most ics in regular use are quite tolerant and earthing your hands by touching a metal water pipe or window frame before handling them will be adequate. The easiest of the cmos ic frequency dividers is the 4013 and this consists of two d type flip flops.
We call it cmos complementary mos.
Cmos is the shortened form for complementary metal oxide semiconductor and it is a technology for fabricating the ic s which are used in various applications. Some family the same number as the ttl. In 1968 the original 4000 series was introduced by rca. The input is then placed on the clock terminal and the output is extracted from the q output.
