By Sandeep Verma – August 31, If C is set to low, then F will be Y3. This type of decoder asserts exactly one of its n output bits, or none of them, for every integer input value.

And in reality which way you choose will likely depend on what chips you have available. I implement the function using a normal 3×8 decoder but I think it is not the best way to do that and I also need to use 74LS Because each line in the truth table corresponds to a specific output, and because each line in the table is unique, then we have the eight unique switching expressions that we need: May Learn how and when to remove this template message.

Functionality it can be described as: Sign up using Facebook.

Some decoders have less than 2 n output lines; in such cases, at least one output pattern will be repeated for different input values. The “address” bit number of the activated output is specified by the integer input value.
