DESCRIPTION
The SN65HVDA540/SN65HVDA541 meets or
exceeds the specifications of the ISO 11898 standard
for use in applications employing a Controller Area
Network (CAN). The device is qualified for use in
automotive applications.
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⁾.
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.
(1) The signaling rate of a line is the number of voltage
transitions that are made per second, expressed in the units
bps (bits per second).
