The following is a list of 7400-series digital logic integrated circuits. In the mid-1960s, ... Datasheet 74x4002 2 dual 4-input NOR gate 14 CD74HC4002: 74x4015 2
The first part number in the series, the 7400, is a 14-pin IC containing four two-input NAND gates. Each gate uses two input pins and one output pin, with the remaining two pins being power (+5 V) and ground. This part was made in various through-hole and surface-mount packages, including flat pack and plastic/ceramic dual in-line.
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 74S181 4-bit ALU bitslice resting on a page from the datasheet. The 74181 is a 4-bit slice arithmetic logic unit (ALU), implemented as a 7400 series TTL integrated circuit. Introduced by Texas Instruments in February 1970, [1] it was the first complete ALU on a single chip. [2]
A logic gate is a device that performs a Boolean function, a logical operation performed on one or more binary inputs that produces a single binary output. Depending on the context, the term may refer to an ideal logic gate , one that has, for instance, zero rise time and unlimited fan-out , or it may refer to a non-ideal physical device [ 1 ...
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 [4] SN54LS54 = single 2-3-3-2 AOI gate [9]
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.
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.
