Thread: 8-to-255 address decoder out of ttl

Hello,
I need to make a 8 to 255 decoder for educational pusposes out of ttl.

I am thinking of using the 74ls154 on the next scheme:

1. One 74ls154 decodes 4 to 16.
2. It's inputs, will be the 4 lower bits on the total of 8 of the decoder.
3. Each of the 16 outputs of this first 74ls154, is connected to the enable pins (G1, G2, active low) of each of another 16 74ls154 ICs.
4. All 4 inputs of these other 16 74ls154 will be connected together in parallel (common bus).
5. These 4 inputs will be the 4 higher bits on the total of 8 of the decoder.

Will this work?
If yes, I guess I need just 17 of these 74ls154 ICs?
