The SN65HVD23x 3.3 V CAN transceivers provide the interface between the 3.3 V µPs, MCUs and DSPs and the differential bus lines, and are designed to transmit data at signaling rates up to 1 Mbps as defined by the ISO 11898 standard.

To ensure reliable operation at all data rates and supply voltages, the V_CC supply pin of each CAN transceiver should be decoupled with a 100-nF ceramic capacitor located as close to the V_CC and GND pins as possible. The TPS76333 is a linear voltage regulator suitable for supplying the 3.3-V supply.
