DESCRIPTION
The SN65HVD233, SN65HVD234, and SN65HVD235 are used in applications employing the controller area network (CAN) serial communication physical layer in accordance with the ISO 11898 standard. As a CAN transceiver, each provides transmit and receive capability between the differential CAN bus and a CAN controller, with signaling rates up to 1 Mbps. Designed for operation in especially harsh environments, the devices feature cross-wire, overvoltage and loss of ground protection to ±36 V, with overtemperature protection and common-mode transient protection of ±100 V. These devices operate over a 7-V to 12-V common-mode range with a maximum of 60 nodes on a bus.

DESCRIPTION (Continued)
If the common-mode range is restricted to the ISO-11898 Standard range of 2 V to 7 V, up to 120 nodes may be connected on a bus. These transceivers interface the single-ended CAN controller with the differential CAN bus found in industrial, building automation, and automotive applications. The RS, pin 8 of the SN65HVD233, SN65HVD234, and SN65HVD235 provides for three modes of operation: high-speed, slope control, or low-power standby mode. The high-speed mode of operation is selected by connecting pin 8 directly to ground, allowing the driver output transistors to switch on and off 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, since the slope is proportional to the pin's output current. Slope control is implemented with a resistor value of 10 k to achieve a slew rate of 15 V/us and a value of 100 k to achieve 2.0 V/µs slew rate. For more information about slope control, refer to the application information section. The SN65HVD233, SN65HVD234, and SN65HVD235 enter a low-current standby mode during which the driver is switched off and the receiver remains active if a high logic level is applied to pin 8. The local protocol controller reverses this low-current standby mode when it needs to transmit to the bus. A logic high on the loopback LBK pin 5 of the SN65HVD233 places the bus output and bus input in a high-impedance state. The remaining circuit remains active and available for driver to receiver loopback, self-diagnostic node functions without disturbing the bus. The SN65HVD234 enters an ultralow-current sleep mode in which both the driver and receiver circuits are deactivated if a low logic level is applied to EN pin 5. The device remains in this sleep mode until the circuit is reactivated by applying a high logic level to pin 5. The AB pin 5 of the SN65HVD235 implements a bus listen-only loopback feature which allows the local node controller to synchronize its baud rate with that of the CAN bus. In autobaud mode, the driver's bus output is placed in a high-impedance state while the receiver's bus input remains active. For more information on the autobaud mode, refer to the application information section.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
