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
Q. A beam containing two types of charged particles is moving from A to B. Particles of type I with charge +3q, and those of type II with charge -2q (where -q is the charge of an e
how to design a 32:1 multiplexer using two 16:1 multiplexers and a 2:1 multiplexer?
PNP The other kind of BJT is the PNP with the letters "P" and "N" standing for the majority charge carriers inside the dissimilar regions of the transistor. Figure:
The LEDs should also show the rounded percentage of the full scale output. Since there are 8 LEDs every one represents 12.5%. Though, since we want the rounded percentage the LED o
