SN65HVDA540: No Wake Up
SN65HVDA541: Wake Up Powered By VIO
Supply So VCC (5 V) Supply May Be Shut
Down to Save System Power
As a CAN transceiver, this device provides differential
transmit capability to the bus and differential receive
capability to a CAN controller at signaling rates up to
1 megabit per second (Mbps)(1).

High Electromagnetic Immunity (EMI)
Low Electromagnetic Emissions (EME)
Protection
Designed for operation in especially harsh
environments, the SN65HVDA540/SN65HVDA541
features cross-wire, bus over voltage, loss of ground
protection, over temperature thermal shut down
protection, and a wide common-mode range.
