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 ...

A tri-state type DIP switch can be in one of three positions (+, 0, −) which allows more codes than a binary DIP switch. For example, 8 pole tri-state DIP switches offer 6,561 (3 8) combinations/codes compared to 8 pole binary switches' 256 (2 8) combinations/codes. This makes them especially suitable for encoding devices such as a remote ...
Skinny dual in-line package (SDIP or SPDIP [6]) – Sometimes used to refer to a "narrow" 0.300 in. (or 300 mil) wide DIP, normally when clarification is needed e.g. for DIP with 24 pins or more, which usually come in "wide" 0.600 in wide DIP package. An example of a typical proper full spec for a "narrow" DIP package would be 300 mil body ...
A very early CD4029A counter IC, in 16-pin ceramic dual in-line package (DIP-16), manufactured by RCA Colorized IC die and schematics of CD4011BE NAND gateThe 4000 series was introduced as the CD4000 COS/MOS series in 1968 by RCA [1] as a lower power and more versatile alternative to the 7400 series of transistor-transistor logic (TTL) chips.
The 74S181 4-bit ALU bitslice resting on a page from the datasheet. The 74181 is a 4-bit slice arithmetic logic unit (ALU), implemented as a 7400 series TTL integrated circuit. Introduced by Texas Instruments in February 1970, [1] it was the first complete ALU on a single chip. [2]
The pin assignment of this early series differed from the de facto standard set by the later series in DIP packages (in particular, ground was connected to pin 11 and the power supply to pin 4, compared to pins 7 and 14 for DIP packages). [5]
The 4-bit A register (accumulator) is the source and destination register for most arithmetic, logic, and data memory access operations. It can also be used to load the Br and Bd portions of the B register, to load and input 4 bits of the 8-bit Q latch data, to input 4 bits of the 8-bit L port and to perform data exchanges with the SIO register.
