rs232 mux
Has anyone used something like a mpc508 to mux a signal to different devices?
https://focus.ti.com/lit/ds/symlink/mpc508.pdf
I'd like to use the same 4 wire RJ for either
pwr,gnd,RS232 TX, RS232 RX.
or
pwr,gnd,RS485 A, RS485 B
So I wanted to know if some kind of mux exits for a RS232 level?
ps my board is 5V.
Currently I will just use some jumper to route the signal to either MAX232 or MAX485 chip.
