Power Supply Connection:
- Connect the Vcc pin to a stable power supply within the operating range of 3.0V to 5.5V.
- Ensure the GND pin is connected to the system ground.
Enable Pin (EN):
- The EN pin controls the active or standby state of the device.
- Set EN high (Vcc) to enable the transceiver.
- Set EN low (GND) to put the device into low-power standby mode.
Data Transmission:
- Use the TXD and RXD pins for data transmission and reception.
- Ensure the baud rate does not exceed 1 Mbps for reliable communication.
Termination Resistors:
- For optimal performance, connect a 120Ω termination resistor between CAN_H and CAN_L at both ends of the bus.
Temperature Considerations:
- Operate the device within the temperature range of -40°C to 125°C to ensure reliability and longevity.
Electrostatic Discharge (ESD) Protection:
- Handle the device with appropriate ESD precautions to prevent damage.
Mounting and Layout:
- Follow recommended PCB layout guidelines to minimize noise and interference.
Signal Integrity:
- Keep signal traces as short as possible to maintain signal integrity, especially for high-speed applications.
