The SN prefix indicates it was manufactured by Texas Instruments [1] The N suffix is a vendor-specific code indicating plastic DIP packaging. The second line of numbers (7645) is a date code; this chip was manufactured in the 45th week of 1976. [2] The 7400 series is a popular logic family of transistor–transistor logic (TTL) integrated ...
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.
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] It was used as the arithmetic/logic core in the CPUs of many historically significant minicomputers and other devices.

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 ...
Texas Instruments introduced the 7400 series TTL family in 1964. Transistor–transistor logic uses bipolar transistors to form its integrated circuits. [12] TTL has changed significantly over the years, with newer versions replacing the older types.
(Reuters) -Texas Instruments said on Friday it would receive up to $1.6 billion in funding from the U.S. Commerce Department towards the construction of three new facilities, the latest government ...
The 7400 series of transistor-transistor logic chips, developed by Texas Instruments in the 1960s, popularized the use of integrated circuits in computer logic. The military-grade version of this was the 5400 series.
