How to add Extra inputs to Logic gates

How to add Extra inputs to Logic gates. I am using HCF 4068B having 8 inputs and single output ..

I want the input made into 10 or 12 pins or more than that how to doit

Please reply and for other logic gates

Thanks you

One do not "add" input to an existing gate, in this case 4068 an 8-input NAND.

However, one can use extra logic gates to accept more logic signals before feeding to one or more inputs of the final 4068 NAND gate.

For example, one can use a 4082 Dual-4 AND gate, which has eight inputs and two outputs. By connecting these two outputs to the input of the 4068, one therefore has essentially 8(from 4082) + 6(from 4068) = 14 inputs.
