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?

\$\begingroup\$ If this is a homework problem, what have you figured out so far? If not, you must have some specific part in mind, so a link to the datsheet is required. In fact it will depend on the details of the implementation. \$\endgroup\$– Spehro 'speff' PefhanyCommented Oct 14, 2016 at 22:21

\$\begingroup\$ I have reached an answer using enable property but can't find an IC with enable in the market and I need to implement it so how can I do it? and the datasheet is here ti.com/lit/ds/sdls109/sdls109.pdf \$\endgroup\$– Mohamed MahmoudCommented Oct 14, 2016 at 23:23

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.
