Describe 74LS139 memory decoder.
The 74LS139 is a dual 2-to-4 line decoder. This contains two separate 2-to-4 line decoders - all with its address, output and enable connections.
The Pin-out of the 74LS139
Analysis Flow Similar to most subjects, the analysis of semiconductor devices is also performed by starting from simpler problems and regularly progressing to more complex one
