The 74181 is a 4-bit slicearithmetic logic unit (ALU), implemented as a 7400 seriesTTLintegrated circuit. Introduced by Texas Instruments in February 1970, it was the first complete ALU on a single chip. It was used as the arithmetic/logic core in the CPUs of many historically significant minicomputers and other devices. The 74181 represents an evolutionary step between the CPUs of the 1960s, …
