In computer engineering, a logic family is one of two related concepts: . A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates constructed using one of several different designs, usually with compatible logic levels and power supply characteristics within a family.
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
CMOS inverter (a NOT logic gate). Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", / s iː m ɑː s /, /-ɒ s /) 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.

The first CMOS gate arrays were developed by Robert Lipp, [5] [6] in 1974 for International Microcircuits, Inc. (IMI). [3] Metal–oxide–semiconductor (MOS) standard-cell technology was introduced by Fairchild and Motorola, under the trade names Micromosaic and Polycell, in the 1970s.
Same technology as the 74S family, but with "miller killer" circuitry to speed up low-to-high transitions. TTL logic levels. [29]: 2–5 CMOS and BiCMOS families [b] 74C CMOS: 3.0–15 V 60 ns 0.36 mA −0.36 mA 1975 [30]: 1 74C is standard CMOS, similar to buffered 4000 (4000B) series. Input levels not compatible with TTL families.
Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors.Its name signifies that transistors perform both the logic function (the first "transistor") and the amplifying function (the second "transistor"), as opposed to earlier resistor–transistor logic (RTL) and diode–transistor logic (DTL).
As semiconductor technology has progressed, LVCMOS power supply voltage and interface standards for decreasing voltages have been defined by the Joint Electron Device Engineering Council for digital logic levels lower than 5 volts.
Some manufacturers released some 4000-series equivalent CMOS circuits with a 74 prefix, for example, the 74HC4066 [2] was a replacement for the 4066 with slightly different electrical characteristics (different power-supply voltage ratings, higher frequency capabilities, lower "on" resistances in analog switches, etc.).
