The SN65HVD251 is intended for use in applications employing the Controller Area Network (CAN) serial
communication physical layer in accordance with the ISO 11898 Standard. The SN65HVD251 provides
differential transmit capability to the bus and differential receive capability to a CAN controller at speeds up to 1
megabits per second (Mbps).
Designed for operation in harsh environments, the device features cross-wire, over-voltage and loss of ground
protection to
36 V. Also featured are over-temperature protection as well as -7 V to 12 V common-mode range,
and tolerance to transients of
200 V. The transceiver interfaces the single-ended CAN controller with the
differential CAN bus found in industrial, building automation, and automotive applications.
Rs, pin 8, provides for three different modes of operation: high-speed, slope control, or low-power mode. The
high-speed mode of operation is selected by connecting pin 8 to ground, allowing the transmitter output
transistors to switch as fast as possible with no limitation on the rise and fall slope. The rise and fall slope can be
adjusted by connecting a resistor to ground at pin 8; the slope is proportional to the pin's output current. Slope
control with an external resistor value of 10 k
gives ~ 15 V/us slew rate; 100 k
gives ~ 2 V/us slew rate.
If a high logic level is applied to the Rs pin 8, the device enters a low-current standby mode during which the
driver is switched off and the receiver remains active . The local protocol controller reverses this low-current
standby mode when it needs to transmit to the bus.
The SN65HVD251 may be used in CAN, DeviceNetTM or SDSTM applications with the Texas Instruments'
TMS320F241 and TMS320F243 DSPs with CAN 2.0B controllers.
