Instructions for Use:

1. Power Supply:

   • Ensure that the supply voltage (V_CC) is within the range of 4.75V to 5.25V.
   • Connect the ground (GND) pin to the system ground.

2. Standby Mode:

   • To enter standby mode, set the STBY pin high.
   • The device will draw a very low current (typically 0.06mA) in this mode.

3. CAN Bus Connection:

   • Connect the CANH and CANL pins to the CAN bus lines.
   • Ensure that the differential input voltage (V_DIFF) does not exceed 卤2V and the common-mode input voltage (V_CM) stays within -2V to 7V.

4. Data Transmission:

   • The device supports a maximum data rate of 1Mbps.
   • Ensure that the output voltage levels (V_OH and V_OL) meet the required specifications for the connected CAN controller.

5. Temperature Considerations:

   • The operating temperature range is from -40掳C to 125掳C.
   • Store the device within the storage temperature range of -65掳C to 150掳C.

6. Capacitance:

   • The input and output capacitances are typically 10pF. Ensure that any external capacitors do not significantly affect these values.

7. Electrostatic Discharge (ESD) Protection:

   • Handle the device with care to avoid ESD damage.
   • Use appropriate ESD protection measures during handling and installation.

8. PCB Layout:

   • Place the device close to the CAN bus lines to minimize noise and improve signal integrity.
   • Use proper grounding techniques to ensure stable operation.
