The following is a list of 7400-series digital logic integrated circuits. In the mid-1960s, the original 7400-series integrated circuits were introduced by Texas Instruments with the prefix "SN" to create the name SN74xx. Due to the popularity of these parts, other manufacturers released pin-to-pin compatible logic devices and kept the 7400 ...
The first part number in the series, the 7400, is a 14-pin IC containing four two-input NAND gates. Each gate uses two input pins and one output pin, with the remaining two pins being power (+5 V) and ground. This part was made in various through-hole and surface-mount packages, including flat pack and plastic/ceramic dual in-line.
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 ...
Plastic leaded chip carrier (PLCC): square, J-lead, pin spacing 1.27 mm. Quad flat package (QFP): various sizes, with pins on all four sides. Low-profile quad flat-package (LQFP): 1.4 mm high, varying sized and pins on all four sides. Plastic quad flat-pack (PQFP), a square with pins on all four sides, 44 or more pins.

Extremely small surface-mount technology parts often bear only a number used in a manufacturer's lookup table to find the integrated circuit's characteristics. The manufacturing date is commonly represented as a two-digit year followed by a two-digit week code, such that a part bearing the code 8341 was manufactured in week 41 of 1983, or ...
The LM series originated with integrated circuits made by National Semiconductor. [2][3] The prefix LM stands for linear monolithic, referring to the analog components integrated onto a single piece of silicon. [4] Because of the popularity of these parts, many of them were second-sourced by other manufacturers who kept the sequence number as ...
The 555 timer IC is an integrated circuit used in a variety of timer, delay, pulse generation, and oscillator applications. It is one of the most popular timing ICs due to its flexibility and price. Derivatives provide two (556) or four (558) timing circuits in one package. [ 2 ] The design was first marketed in 1972 by Signetics [ 3 ][ 4 ] and ...
