Show how to build each of the following single or
multiple-output logic functions using one or more 74X138 or 74X139
binary decoders and NAND gates. (Hint: Each realization should be
equivalent to a sum of minterms.)
F=PI,A,B,C,D(8,11,12,15).
DO NOT ANSWER IF YOU ARE NOT SURE!
Homework Answers
this implementation is done using 74x138 decoder.
When using "PI" the outputs are rather inverted wherein the terms other than (8,11,12,15) are combined into a OR gate,
