Need Appropriate Multiplexer

Hello,

I have attached a file which depicts the type of Multiplexer I'm looking for. It takes an 8051's(microcontroller) transmit and receive signals and needs to route to three different chips.(RS422, USB Type A, USB Type B) I want the mux to only route it to one of the chips at a time using a couple control lines.

I have searched digikey..mouser and haven't found what I'm looking for. Is there anything I'm missing. Seems like it's a pretty simple one?

ps. This is a 5V system which is sending keyboard/trackball data so the baud rate is extremely slow. The chips will connect up directly to each host.

Thanks!

Since I haven't received any replies is there information i'm leaving out? Or am I presenting my issue in a bad way? I just want to figure out how to better convey my information to you guys so I can get help and give help better. Any suggestions?

hi,
Look at the HEF4051... 52 & 53 analog selectors.
