SN65HVD233

SN65HVD234

SN65HVD235

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.

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.

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

Ω to achieve a slew rate of 915 V/

µs and a value of 100 kΩ to achieve 9 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.
