Buying advice

When selecting a communication IC, consider the required protocol (e.g., CAN, RS-485, I2C, RF), power consumption, data rate, and noise immunity. Ensure compatibility with your microcontroller's voltage levels and interface (SPI, I2C, UART). For industrial environments, prioritize transceivers with robust protection against ESD and interference.
