The TCAN4420 device is designed to operate with a main V_CC input voltage supply range between 4.5 V and
5.5 V. The device also has an IO level shifting supply input, V_IO, designed for a range between 2.8 V and
5.5 V. To ensure reliable operation at all data rates and supply voltages, each supply should be decoupled with a 100-nF ceramic capacitor located as close to the supply pins as possible. This helps to reduce supply voltage ripple present on the outputs of switched-mode power supplies and also helps to compensate for the resistance and inductance of the PCB power planes.
