DESCRIPTION
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
(2)
receive capability for a CAN controller at signaling rates of up to 1 megabit per second (Mbps).
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, a –12 V to 12 V common-
mode range, and will withstand voltage transients from –200 V to 200 V according to ISO 7637.
The STB input (pin 8) selects between two different modes of operation; high-speed or low-power mode. The
high-speed mode of operation is selected by connecting STB to ground.
If a high logic level is applied to the STB pin of the SN65HVD1040, the device enters a low-power bus-monitor
standby mode. While the SN65HVD1040 is in the low-power bus-monitor standby mode, a dominant bit greater
than 5 μs on the bus is passed by the bus-monitor circuit to the receiver output. The local protocol controller may
then reactivate the device when it needs to transmit to the bus.
(2) 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).
