Hello expert,

May I know if we have 1T1R UART to RS232 solution with automotive grade? This is requested by Radar application. The UART output is 1Tx and 1Rx. I only found in select table for TRS3223-Q1 for q grade but it is 2T2R. Thanks a lot!

Best regards,

Ann Lien

The only automotive 1+1 transceiver is the SN65C3221-Q1, which is old and expensive. I would recommend the MAX3232E-Q1/TRS3232E-Q1, or the TRS3223-Q1 if you need auto-powerdown.

Hi Ann,

Clemens is correct as usual. Below is the product lists of RS232 devices with automotive qualification. Only 1 device with 1T1R is qualified.
