Frequently asked questions
What is the price of 74181 4-Bit Arithmetic Logic Unit (ALU) IC 5V DIP-24 Wide in Egypt?
74181 4-Bit Arithmetic Logic Unit (ALU) IC 5V DIP-24 Wide currently costs 75 EGP in Egypt.
Where can I buy 74181 4-Bit Arithmetic Logic Unit (ALU) IC 5V DIP-24 Wide in Egypt?
74181 4-Bit Arithmetic Logic Unit (ALU) IC 5V DIP-24 Wide is available from Makers Electronics. Compare the offers above to find the best price.
Does the 74181 need a clock signal?
No. The 74181 is a combinational logic device, so its outputs change directly with the A and B data inputs, the S0 to S3 select lines, the mode input and the carry input. To store results you need separate registers or flip-flops.
Can the 74181 be connected directly to a 3.3 V microcontroller?
The 74181 is a 5 V TTL device and should be powered from 5 V. Its logic outputs may not reliably drive 3.3 V inputs without a level shifter, so check the logic levels before connecting it to a 3.3 V board.
