# Usage of IC 74138:
ic = IC_74138()
print(ic.__doc__)
This is a 1:8 demultiplexer(3:8 decoder) with output being inverted input
# The Pin configuration is:
inp = {1: 1, 2: 0, 3: 1, 4: 0, 5: 0, 6: 1}
# Pin initinalization
# Powering up the IC - using -- ic.setIC({14: 1, 7: 0})
ic.setIC({16: 1, 8: 0})
# Setting the inputs of the ic
ic.setIC(inp)
# Draw the IC with the current configuration\n
ic.drawIC()
