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 7400 series contains hundreds of devices that provide everything from basic logic gates, flip-flops, and counters, to special purpose bus transceivers and arithmetic logic units (ALU). Specific functions are described in a list of 7400 series integrated circuits. Some TTL logic parts were made with an extended military-specification ...
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 .
A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates constructed using one of several different designs, usually with compatible logic levels and power supply characteristics within a family. Many logic families were produced as individual components, each containing one or a few related basic ...
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 ...

TTL 7400 series gate logic: Memory: 8 kB RAM, 20-bit word Magnetic-core memory: Graphics: 6-1/2 inch display oscilloscope: Sound: None: Connectivity: 2× RS-232, SD-81 Signal Digitizer (100K samples per second), ASR-33 Teletype, NIC-284 paper tape reader, Diablo series 30 disk drive, Bruker XY pen plotter: Power: 115/230 VAC, 50–60 Hz, 250 W ...
The PDS-1 electronics were built from 7400 series low-density TTL integrated circuits, with only a dozen logic gates or 4 register bits per DIP chip. Small printed circuit cards held up to 12 chips each. The shallow desk pedestal held three racks or rows of cards, with 25 cards per row, and a wire wrap backplane connecting all cards. There was ...
