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 sequence number as an aid to identification of compatible parts. However ...
The Soviet Union started manufacturing TTL ICs with 7400-series pinout in the late 1960s and early 1970s, such as the K155ЛA3, which was pin-compatible with the 7400 part available in the United States, except for using a metric spacing of 2.5 mm between pins instead of the 0.1 inches (2.54 mm) pin-to-pin spacing used in the west.

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 ...
The 74181 is a 7400 series medium-scale integration (MSI) TTL integrated circuit, containing the equivalent of 75 logic gates [3] and most commonly packaged as a 24-pin DIP. The 4-bit wide ALU can perform all the traditional add / subtract / decrement operations with or without carry, as well as AND / NAND, OR / NOR, XOR, and shift. Many ...
7400/7410 350–550 MHz, uses AltiVec, a SIMD extension of the original PPC specs 7440/7450 micro-architecture family up to 1.5 GHz and 256 kB on-chip L2 cache and improved Altivec 7447/7457 micro-architecture family up to 1.83 GHz with 512 kB on-chip L2 cache
Three Americans have been released after spending years imprisoned in China, the White House said Wednesday. Mark Swidan, Kai Li and John Leung were released and would soon "return and be reunited ...
Freshman Jeremiah Fears scored a season-high 26 points, Jalon Moore added 24 and Oklahoma held off No. Arizona 82-77 on Thursday in the semifinals of the Battle 4 Atlantis. Duke Miles made a high ...
The soviet integrated circuit designation is an industrial specification for encoding the names of integrated circuits manufactured in the Soviet Union and the Post-Soviet states. 25 years after the dissolution of the Soviet Union, a number of manufacturers in Russia, Belarus, Ukraine, Latvia, and Uzbekistan still use this designation.
