Transistors are added to multiplex VA and VB and result in Vout. Implement this circuit using CD4069 inverters. Think carefully about which terminal goes where! You'll need to use separate ICs for the inverter and the rest of the circuitry because, on a chip, the supply and ground pins are all shorted together. You can use clock frequencies in the tens of kHz range, capacitors in the 10nF range, and a supply of 5V.
