The following is a list of 7400-series digital ... Schematic of 74LS51 IC consists of a 3-3 AOI gate and 2-2 AOI gate. ... parts were available in 7400 TTL families ...
The 7400 series is a popular logic family of transistor–transistor logic (TTL) integrated circuits (ICs). [ 3 ] In 1964, Texas Instruments introduced the SN5400 series of logic chips, in a ceramic semiconductor package .
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 ...
Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors.Its name signifies that transistors perform both the logic function (the first "transistor") and the amplifying function (the second "transistor"), as opposed to earlier resistor–transistor logic (RTL) and diode–transistor logic (DTL).
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 ...
Because of the incompatibility of the CD4000 series of chips with the previous TTL family, a new standard emerged which combined the best of the TTL family with the advantages of the CD4000 family. It was known as the 74HC (which used anywhere from 3.3V to 5V power supplies (and used logic levels relative to the power supply)), and with devices ...
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).
TTL 7400-series logic family: (in past decades, a number of AOI parts were available in the 7400 family, but currently most are obsolete (no longer manufactured)) SN5450 = dual 2-2 AOI gate, one is expandable [6] (SN54 is military version of SN74) SN74LS51 = 2-2 AOI gate and 3-3 AOI gate [5] SN54LS54 = single 2-3-3-2 AOI gate [10]
