Other Parts Discussed in Thread: TS5A3166, , TS5A3167
I am designing a system with an RS485 bus. The bus is <1 m but long enough to require termination in both ends. At one end of the bus there is a main module that always has a fixed termination resistor. Up to 10 expansion modules are then connected to the main module and in the module furthest away from the main module I want a termination resistor to be switched in.
The data rate is 7.5 Mbps and the rise/fall times of the selected transceiver is min 3 ns and max 20 ns. The transceivers are supplied by 3.3 V. The main module and expansion modules share a common ground.
I saw in the thread below that someone was planning to use TS5A3166 for this but I think it is not suitable for my application. This since losing power to one expansion module leads to loss of power to the TS5A3166 which seems to lead to that the TS5A3166 is not high impedance

Is the SN74CB3Q3306A suitable for the application described above or do you propose some other circuit?
