Hi Lady & Gent, Can you help me to identify about TUSB3410? Can I remove SN75LV4737A if I only use SIN and SOUT for data transfer ? Thanks ! David

Hello David,

No, even if you only use SIN/SOUT, you still need the driver to output negative voltage for the RS-232.

Dear Elias,

Thank you so much for answer

I know line driver SN75LV4737A can support tanslateion to +15/-15V from 3.3V/0V.

If I only need to use 3.3V to communicate with other device which has only 3.3V level UART, shall I adopt line driver still ? On ther other hand, both of sides are UART device. Please advise. Thanks !.

Best Regards

David Yang

David,

If your communication is going to be always on 0-to-3.3V, you don't need the driver.
