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, ...
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 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.
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. Many ...
Rather, this article shows how the 7400 series has developed over five decades. As such, in my opinion the list should try to show the 7400 series in its entirety and should specifically include obsolete chips that have long since disappeared from common data books. Very roughly, the numerical order of chips also represents a chronological order.
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
