Below is the transistor schematic and circuit symbol for atri-state buffer.
a. What is the truth table for this tri-state buffer?
b. How might you build a two input multiplexer using two ofthese tri-state buffers and two inverters? Draw the schematic (youcan use the symbol (above) – you don’t have to draw thetransistors). Does your multiplexer have a restored or anon-restored output? Explain why?
