●The SN65HVD1050 meets or exceeds the specifications of the ISO 11898 standard for use in applications employing a Controller Area Network (CAN).
●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)
●The SN65HVD1050 is designed for operation in especially harsh environments. As a result, the device features cross-wire, overvoltage and loss of ground protection from 27 V 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.
●Pin 8 provides for two different modes of operation: high-speed or silent mode. The high-speed mode of operation is selected by connecting S (pin 8) to ground.
●If a high logic level is applied to the S pin of the SN65HVD1050, the device enters a listen-only silent mode during which the driver is switched off while the receiver remains fully functional.
●In silent mode, all bus activity is passed by the receiver output to the local protocol controller. When data transmission is required, the local protocol controller reverses this low-current silent mode by placing a logic-low on the S pin to resume full operation.
●A dominant time-out circuit in the SN65HVD1050 prevents the driver from blocking network communication with a hardware or software failure. The time-out circuit is triggered by a falling edge on TXD (pin 1). If no rising edge is seen before the time-out constant of the circuit expires, the driver is disabled. The circuit is then reset by the next rising edge on TXD.
●Vref (pin 5) is available as a VCC/2 voltage reference to stabilize the output common mode voltage point.
●The SN65HVD1050 is characterized for operation from 40°C to 125°C.
