Electrical – Implementing 4-16 decoder using BCD to decimal (4-10) decoder


Is it possible to implement a 4-16 decoder using BCD to decimal decoders without using enables and how can I go on doing this?

I'm not going to give you the complete solution since this is clearly homework, but you can see the key implementation detail that I mentioned in the comment right at the top of the datasheet:

This is an old-fashioned TTL/LSTTL type of circuit where the selected output is active 'low':

So the answer to 'is it possible' is 'yes' in this particular instance.
