Hi team,

My customer use MAX3221E to complete the conversion from RS422 to TLL to RS232.

Below is the schematic, could you please help review and give suggestions?

Thank you.

Ivy,

What's the data rate and communication distance of the application? It might be more important to have a termination at the RX of RS422 than the pull up or pull down (the device has integrated the fail-safe feature). The rest of the schematic looks good to me. BTW, you can refer this TI design for the similar function.
