DESCRIPTION

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 kΩ gives ~ 15 V/us slew rate; 100 kΩ 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, DeviceNet™ or SDS™ applications with the Texas Instruments'

TMS320F241 and TMS320F243 DSPs with CAN 2.0B controllers.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
