thank you all for the feedback, I really appreciate all the help. what I learned from the replies that the 74LS47 is useless in my case.
I thought about something else, which is using a 4-to-16 decoder that takes 4 inputs and gives (16 outputs).
each output will go throw another demultiplexer "or any device you guys suggest" for example it has 1 input and has 7 outputs "which I'll connect directly to the 7 segment".
for example, I entered bcd "0000" the first line in the decoder will be enabled then that line will go throw the demultiplexeer "or other device" and enables certian lines that I'll connect to the 7 segment display like this. Image
To be honest I don't think the demultiplexer will help, I want a device that can help me enable some lines or not, at least enables everything then I'll use an inverter to disables the ones that I don't need.
My ideas are kinda blurry and not clear about this, so bare with me guys.
thanks.
