For example, early digital clocks or electronic calculators may have used one or more PMOS devices to provide most of the logic for the finished product. The F14 CADC, Intel 4004, Intel 4040, and Intel 8008 microprocessors and their support chips were PMOS. Of these families, only ECL, TTL, NMOS, CMOS, and BiCMOS are currently still in ...
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 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 ...
The Television Interface Adaptor, the custom graphics and audio chip developed for the Atari 2600 in 1977. [97] MOS Technology SID, a programmable sound generator developed for the Commodore 64 in 1982. [97] MOS Technology VIC-II, a video display controller developed for the Commodore 64 in 1982 (5 μm). [97]
Both of these examples are specific to an application (which is typical of an ASIC) but are sold to many different system vendors (which is typical of standard parts). ASICs such as these are sometimes called application-specific standard products (ASSPs). Examples of ASICs are Ethernet network interface controller, flash memory controller, etc.
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).
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.).
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.
