Description

1 Piece
The 74181 is a 4-bit slice arithmetic logic unit, implemented as a 7400 series TTL integrated circuit. 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 starting point for the student of microprocessor internals often lies in the past. The technology of the early 1970s holds the fundamentals from which a modern processor can be understood, but remains simple enough to grasp in its entirety as a beginner. Registers, instruction decoders, counters, and an arithmetic/logic unit, or ALU. And for decades the 74181, as an all-in-one 4-bit ALU on a chip that you might have found in a minicomputer at the turn of the 1970s, represented the most convenient way to teach the operation of these devices. Electronic engineers and computer scientists of all ages will have encountered them as they gained their qualifications. 
Please Note!
The only manufacturer ID on the chip are the letters SW and coincidentally the only datasheet found was from Signetics, so SW may be Signetics but we are not definite about this.

These genuine vintage parts came to us as part of a lot of surplus stock from a large ‘Milspec’ type Co.

Having been in storage for many years (date coded 7327) we have classified them as ‘new other’.

Stored with us still in their original tubes, you will receive the qty ordered in a cut length of tube.

They are as new and will work perfectly.

Surplus Stock ?????
