Since you are going between logic inputs and outputs, the most obvious choice to me would be to use another logic chip.
Look at the 74HC157 and 74HC158.
If you want to stay with the analog switch idea, the 74HC4053, would work.
As far as wanting to use low RON switches, there is probably no need to worry. Unless you have something else loading the output of the switch, the microamps of bias current of the logic inputs can tolerate many thousands of ohms. Higher resistance will slow the signal down, but the difference will be well below a microsecond.
