TTL 2 to 4 decoder - demultiplexer

Converting two bit binary input to 4 outputs.
Using discrete components, inspired by TTL logic chips builds.

The two inputs go through double inverters to generate opposite levels.
Those are going to four AND gates (actually NAND + NOT)
The outputs of those go to the output drivers for display.

In my case, it will be scaled up to 4 to 16 decoder to drive a 7 segment display via a diode matrix.
