RS422 to 5V and 3.3VTTL level, I use MAX485/MAX3485, the speed is only 10M, is there a faster chip, the faster the better, please recommend!!!

RS422 and RS485 do not have such high speed, right? Where is your RS422 used? Why does it need such high speed?

1 Features Meets or exceeds TIA/EIA-422-B and ITU Recommendation V.11 Operates from a single 3.3V supply Switching frequency up to 32MHz ESD protection on RS422 bus pins (see ESD Ratings) Low power dissipation: 27mW (typical) Open-circuit fail-safe ±7V common-mode input voltage range with ±200mV sensitivity Accepts 5V logic input and 3.3V supply (enable input) Input hysteresis: 35mV (typical) Pin-for-pin compatible with AM26C32 and AM26LS32 Ioff supports partial power-down mode operation

Find this chip and try it

Go to MAXIM's official website to choose a model. There are high-speed models. However, RS422/485 is not suitable for high-speed communication. Its characteristics are long distance, high reliability and low cost. If you want high-speed communication, you should choose Ethernet. 100M and 1000M are both easy.

I use MAX487
