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 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 .
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

Several members of the 7400 series of integrated circuits can be used as address decoders. For example, when used as an address decoder, the 74154 [ 3 ] provides four address inputs and sixteen (i.e., 2 4 ) device selector outputs.
The 7400 series devices have been produced on a number of different manufacturing processes, but have retained the same pinouts throughout. For example, all 7405 devices provide six NOT gates (or inverters) but may have incompatible supply voltage tolerances.
