These devices are designed to operate from main V_CC input voltage supply range between 4.5 V and 5.5 V. Some devices have an output level shifting supply input, V_RXD, designed for a range between 2.8 V and 5.5 V. Both supply inputs must be well regulated. A bulk capacitance, typically 4.7 μF, should be placed near the CAN transceiver's main V_CC supply terminal in addition to bypass capacitors. A bulk capacitance, typically 1 μF, should be placed near the CAN transceiver's V_RXD supply terminal in addition to bypass capacitors.
