APPLICATION INFORMATION
interoperability with 5-V CAN systems
It is essential that the 3.3-V HVD230 family performs seamlessly with 5-V transceivers because of the large
number of 5-V devices installed. Figure 36 displays a test bus of a 3.3-V node with the HVD230, and three 5-V
nodes: one for each of TI’s SN65LBC031 and UC5350 transceivers, and one using a competitor X250
transceiver.
