How it works
There's a MUX that takes it's inputs from inputs 0 and 1. A clock signal is used as the select pin. The MUX output is present on output 0. Inputs 0 and 1 are also forwarded to outputs 1 and 2.
How to test
Apply clock signal. Outputs 1 and 2 should reflect inputs 0 and 1. Half of the cycle, input 0 should be present on output 0, while input 1 is present on output 0 at the other half of the cycle.
