  • Be aware that the datasheet says “The drivers are inverting level transmitters that convert TTL or CMOS logic levels to ± 5.0V EIA/TIA-232 levels inverted relative to the in- put logic levels.”. So, it wont work in serial communication between RS232-ttl (like in beaglebone(3.3V) with arduino(5V) or raspberrypi(3.3v) with arduino). Since it inverts the bits, it will also invert the start and stop bits, messing up with the serial protocol.
