The SN65HVD1040 meets or exceeds the specifications of the ISO 11898 standard for use in applications employing a Controller Area Network (CAN). As CAN transceivers, these devices provide differential transmit and receive capability for a CAN controller at signaling rates of up to 1 megabit per second (Mbps).⁽¹⁾

Designed for operation in especially harsh environments, the device features ±12 kV ESD protection on the bus and split pins, cross-wire, overvoltage and loss of ground protection from -27 to 40 V, overtemperature shutdown, a -12 V to 12 V common-mode range, and will withstand voltage transients from -200 V to 200 V according to ISO 7637.

⁽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).
