The SN65HVDA1040A 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)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)⁽¹⁾.

The device is designed for operation in especially harsh environments and includes many device protection features such as undervoltage lock out, over temperature thermal shutdown, wide common-mode range and loss of ground protection.
