The only transceiver that can run with a 1.8 V supply is the TRS3122E, with 2/2 drivers/receivers.

If you have a 3.3 V or 5 V supply, you can also use the TRS3227/MAX3227, or TRS3227E/MAX3227E with better ESD protection.

Thanks for the information.

Also i need costing for the part MAX3221E and and MAX3221 for the MOQ(30, 10K and 50K).

I also need to know whether designing a UART to RJ45 debugging console will cause any problems if I use a half-duplex component rather than a full-duplex one.

There are no half-duplex RS-232 transceivers. (And just connecting the DOUT and RIN pins together would change the electrical characteristics to be outside the specification.)

Okay. Please help by sharing the price for the aforementioned components at the aforementioned MOQs.

I am not a TI employee. You can find standard prices on the product page in the "Ordering" table.
