How to use double 2-4 line decoder 74HC139 and double 4-1 data selector?
Answer: No one has answered the 11-year question yet. The seniors are too lazy.
Do you have a single 2-4 decoder? For example, 74HC139 is double 2-4 decoder.
Answer: Non-gate, non-gate, or gate, or non-gate, or D flip-flop, etc. all have single-door devices, but 2-4 decoder does not seem to have single-door. You can package with SOIC-16 patch slightly smaller than double-in-line.
Why is my DXP drawing 74HC573 and 139 different from the reality?
Answer: First of all, you check whether the package of 74 is regular DIP20. If so, then DIP20 in your library can be used unless there is a problem with DIP20 in your library!!
