TRS3122E: unused drivers

Jomer Deogracias

Part Number: TRS3122E

What do you advise regarding the unused drivers and receivers? If I leave it unconnected(float), will it have adverse effects on the circuit? Should I connect it to ground or VL or VCC?
Thanks!

    Jomer,

    By RS232 standard, RX input has 5kOhm resistance to gnd. In DIN pins, there is a weak pull down (about 2MOhm) as well. If you think the bias is not strong enough, you can either connect it to VL or gnd. Please let me know if you have any questions.

    Regards,
