Other Parts Discussed in Thread: TRS3221 , MAX3221 Hi Team,
My customer asked what the difference between MAX3221 and TRS3221? It looks exactly the same on the datasheet. I wonder if you can help me explain it. Thanks!

Hi Zoey,
Thanks for reaching out.
I am copying below an E2E blog which describes all the key factors involved in choosing a digital isolator. Most of these factors are isolation related and hence, remain the same across application whether one needs digital…
Other Parts Discussed in Thread: TRS3221 , MSP430F135 , MAX3232 Hello, I'm trying to connect my MCU to RS232 ports.
This is the schematic.
I'm not using EK or DK board. The DOUT, RIN is connected to the RS232 pins using a USB to serial cable.
…
The TRS3221 is the same.
I doubt that better ESD protection is possible with the same die.
You can also consider TRSF3221(E) and SN65C3221(E)/SN75C3221(E) with higher speeds.

One customer hope to compare and check detailed changed spec Newly datasheet (Rev P) and Old datasheet (Rev O) of MAX3221, but I didn't find Rev O on web search.
Please attach Rev O datasheet…
Hey William,
This is an application diagram from the datasheet of the TRS3221. It is a drop in compatible device to the SN65C3221.
Let me know if you need anything else.
Best,

Part Number: TRS3122E Other Parts Discussed in Thread: TRS3221 , Hi team,
I'm looking for an RS-232 Transceiver, single Tx/Rx, data rate of 250kbps or higher, and in a QFN package. Main supply voltage down to 3.3V will work.
Thank you.
Austria,
I don't recommend software switching the 120 ohm on board. The load is only used at the ends of the cable and the software doesn't know if the connection is at an end or not. The person who runs the cable should add 120 ohm externally at the…
