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.
Specific functions are described in a list of 7400 series integrated circuits. Some TTL logic parts were made with an extended military-specification temperature range. These parts are prefixed with 54 instead of 74 in the part number. The less-common 64 and 84 prefixes on Texas Instruments parts indicated an industrial temperature range. Since ...
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.
The Sylvania parts were used in the controls of the Phoenix missile. [3] TTL became popular with electronic systems designers after Texas Instruments introduced the 5400 series of ICs, with military temperature range, in 1964 and the later 7400 series, specified over a narrower range and with inexpensive plastic packages, in 1966.

The view and element placement of the popular chip 7400. The chip contains four logical elements AND-NOT (NAND). The two additional contacts supply power (+5 V) and connect the ground.
Mayer and Milner arranged to speak to the chip's designer, Chuck Peddle, on using the 6502 as the basis for their programmable video game console. Over the course of a couple of days, the basic design of the Atari VCS was laid out, with Peddle offering Atari the use of the lower-cost MOS Technology 6507 processor and the MOS Technology 6532 RAM ...
7400 series TTL chips. A swappable EPROM chip and a socket (for firmware updates). A 32 KB CMOS SRAM (upgradable to a 64 KB chip) Game controller and VGA ports. USB port and cable for power. A game controller similar to the NES one. A keyboard controller with built-in non-volatile memory. Resistors, capacitors and diodes. A set of 4 ...
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 ...
