Need MAX232's and 4 pin 1/8" plug - swap?
 

I need 2 MAX232 level converters (DIP package).

Would like to swap for them. Have 2 MAX489CPD's
(RS485 transceivers) et al.
What do you need if these are not usable?
(active or passive parts, etc.)

Also need 2 4-pin 1/8" (3.5 mm) plugs.


Thanks for any offer,
