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 4000 series is a CMOS logic family of integrated circuits (ICs) first introduced in 1968 by RCA. [1] It was slowly migrated into the 4000B buffered series after about 1975. [ 2 ] It had a much wider supply voltage range than any contemporary logic family (3V to 18V recommended range for "B" series).

The first CMOS family of logic integrated circuits was introduced by RCA as CD4000 COS/MOS, the 4000 series, in 1968. Initially CMOS logic was slower than LS-TTL. However, because the logic thresholds of CMOS were proportional to the power supply voltage, CMOS devices were well-adapted to battery-operated systems with simple power supplies.
These parts are prefixed with 54 instead of 74 in the part number. [1] A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had been dropped from the TI literature by 1973. Most recent 7400-series parts are fabricated in CMOS or BiCMOS technology rather than TTL.
4000 series is an industry-standard family of integrated circuits. 4000 series may also refer to: ... Radeon HD 4000 series, a series of graphics processing unit;
HCMOS ("high-speed CMOS") is the set of specifications for electrical ratings and characteristics, forming the 74HC00 family, a part of the 7400 series of integrated circuits. [ 1 ] The 74HC00 family followed, and improved upon, the 74C00 series (which provided an alternative CMOS logic family to the 4000 series but retained the part number ...
As Moore's Law continued to drive the industry towards more complex chip designs, the expected widespread move from 8-bit designs of the 1970s to 16-bit designs almost didn't occur; instead, new 32-bit designs like the Motorola 68000 and National Semiconductor NS32000 emerged that offered far more performance.
