Based on the setting above, if BOTH LINE1 and LINE2 inputs are routed to the output at the same time, then the two switches used for
the connection short the two input signals together on the output pins. The shorting resistance between the two input pins is two times
the bypass switch resistance (Rdson). In general this condition of shorting should be avoided, as higher drive currents are likely to occur
on the circuitry that feeds these two input pins of this device.
