Since there are numerous 7400-series parts, the following groups related parts to make it easier to pick a useful part number. This section only includes combinational logic gates. For part numbers in this section, "x" is the 7400-series logic family, such as LS, ALS, HCT, AHCT, HC, AHC, LVC, ... Normal inputs / push–pull outputs
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 .
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 ...

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 ...
A 2716 has 12 address lines and 8 data lines, so it can be programmed to emulate a quad 3-input logic gate IC or a hex 2-input logic gate IC. So a 74S262 could be a TTL logic part. However, the claim above that it is a "character generator ROM" leads me to believe that it is actually a ROM with a character set in it that just happens to have ...
Monolithic Memories, Inc. (MMI) was an American semiconductor company which produced bipolar PROMs, programmable logic devices, and logic circuits (including 7400 series TTL). A team of MMI engineers, under the direction of Ze'ev Drori and headed by John Birkner and H. T. Chua, invented the class of devices known as programmable array logic (PAL).
Going on these figures alone TTL logic gates are limited to perhaps 2 to 10, depending on the type of gate, while CMOS gates have DC fan-outs that are generally far higher than is likely to occur in practical circuits (e.g. using NXP Semiconductor specifications for their HEF4000 series CMOS chips at 25 °C and 15 V gives a fan-out of 34 000).
