Analysis and Synthesis of Logic Functions using Dual 4:1 Multiplexer(IC 74153)

INSTRUCTION

  1. Apply \(V_{CC}\) and low level voltage to ground(GND)
  2. Apply high level voltage to Strobe1G or strobe 2G.
  3. For all the combinations of the select inputs A,B verify that both the LEDs are ON or not.
  4. Follow the truth table in the below section.
  5. Note: Red button symbolize as Low (L), Green button symbolize as High(H).
