Instructions for TJA1021T/20/C 1021T2C

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 4.5V to 5.5V.
   • Connect a decoupling capacitor (typically 100nF) close to the V_CC and GND pins to stabilize the power supply.

2. Standby Mode:

   • To enter standby mode, set the STBY pin to a high state. The device will consume approximately 8渭A in this mode.
   • To return to active mode, set the STBY pin to a low state.

3. Data Transmission:

   • The TJA1021T supports data rates up to 2Mbit/s. For optimal performance, ensure the differential output voltage (V_OD) is within the specified range.
   • Use a 120惟 termination resistor at both ends of the bus to minimize reflections and improve signal integrity.

4. Input Protection:

   • The input voltage range (V_IN) should not exceed 6.0V or drop below -0.5V to avoid damage to the device.
   • The common-mode input voltage range (V_CM) should be between -2V and 7V to prevent damage.

5. Temperature Considerations:

   • The operating temperature range (T_A) is from -40掳C to 125掳C. Ensure the device operates within this range to maintain reliability.
   • The storage temperature range (T_STG) is from -65掳C to 150掳C. Store the device in a dry and cool environment to prevent degradation.

6. ESD Protection:

   • Handle the device with care to avoid electrostatic discharge (ESD). Use ESD-safe tools and workstations when handling the device.

7. Mounting and Layout:

   • Place the device as close as possible to the CAN bus lines to minimize noise and interference.
   • Use a ground plane to provide a low-impedance path for return currents and to shield the device from external noise.

By following these instructions, you can ensure reliable and efficient operation of the TJA1021T/20/C 1021T2C device.
