This opamp buffer has 80-90db isolation.
That is typical at 5 to 10 MHz *if* (i) all of the splitting is done on the input side (i.e., each output has its own op amp), and (ii) the splitter and all of the construction (grounds, shielding, etc.) is done correctly.
If any splitting is done on the output side of the op amp(s), by using one op amp to drive more than one output through separate back terminating resistors, the outputs that share an op amp will only be isolated by 30 to maybe 40 dB (again, assuming that the op amp has been well chosen and all of the construction is done correctly).
