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.
Hi KRZ,
Thanks a lot for your help.
I will have a try without -12V supply on Pin 5, and connect it to Pin 6 on MAX232.
Or, can I used two MAX222s with /EN and /SHDN for signal switching?
Thanks again for your inputs.
