Hi everyone,

 

I need to work on an analog switch which will switch the RS232 (+/- 10VDC) signal from different RS232 serial communication.

 

I tried ADG333 with MAX232IDR, but it will draw too much current when RS232 is in Mark (-8.9VDC), then it will pull it to -0.89VDC.

 

Does everyone how to make analog switch for RS232 signals?

 

Thanks for help.
