APPLICATION INFORMATION
interoperability with 5-V CAN systems
It is essential that the 3.3-V SN65HVD230M family performs seamlessly with 5-V transceivers because of the
large number of 5-V devices installed. Figure 35 displays a test bus of a 3.3-V node with the SN65HVD230M,
and three 5-V nodes: one for each of TI’s SN65LBC031 and UC5350 transceivers, and one using a competitor
X250 transceiver.
