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 kΩ to achieve a slew rate of ≈15 V/us
and a value of 100 kΩ 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.

SLLS557D − NOVEMBER 2002 REVISED JUNE 2005
APPLICATION INFORMATION
Diagnostic Loopback (SN65HVD233)
The loopback (LBK) function of the HVD233 is enabled with a high-level input to pin 5. This forces the driver into a
recessive state and redirects the data (D) input at pin 1 to the received-data output (R) at pin 4. This allows the host
controller to input and read back a bit sequence to perform diagnostic routines without disturbing the CAN bus. A
typical CAN bus application is displayed in Figure 28.
If the LBK pin is not used it may be tied to ground (GND). However, it is pulled low internally (defaults to a low−level
input) and may be left open if not in use.
Autobaud Loopback (SN65HVD235)
The autobaud feature of the HVD235 is implemented by placing a logic high on pin 5 (AB). In autobaud, the
bus-transmit function of the transceiver is disabled, while the bus-receive function and all of the normal operating
functions of the device remain intact. With the autobaud function engaged, normal bus activity can be monitored by
the device. However, if an error frame is generated by the local CAN controller, it is not transmitted to the bus. Only
the host microprocessor can detect the error frame.
Autobaud detection is best suited to applications that have a known selection of baud rates. For example, a popular
industrial application has optional settings of 125 kbps, 250 kbps, or 500 kbps. Once the logic high has been applied
to pin 5 (AB) of the HVD235, assume a baud rate such as 125 kbps, then wait for a message to be transmitted by
another node on the bus. If the wrong baud rate has been selected, an error message is generated by the host CAN
controller. However, since the bus-transmit function of the device has been disabled, no other nodes receive the error
message of the controller.
This procedure makes use of the CAN controller’s status register indications of message received and error warning
status to signal if the current baud rate is correct or not. The warning status indicates that the CAN chip error counters
have been incremented. A message received status indicates that a good message has been received.
If an error is generated, reset the CAN controller with another baud rate, and wait to receive another message. When
an error-free message has been received, the correct baud rate has been detected. A logic low may now be applied
to pin 5 (AB) of the HVD235, returning the bus-transmit normal operating function to the transceiver.

Interoperability With 5-V CAN Systems
ISO−11898 specifies the interface characteristics to a CAN bus with the purpose of insuring interchangeability among
compatible transceivers. While the levels specified in the standard assume a 5-V supply, there is nothing in the
standard that makes this a requirement. The SN65HVD233 is compatible with these requirements with a 3.3-V
supply, assuring interoperability with 5-V supplied transceivers.
Bus Cable
The ISO 11898 Standard specifies a maximum bus length of 40 m and maximum stub length of 0.3 m with a maximum
of 30 nodes. However, with careful design, users can have longer cables, longer stub lengths, and many more nodes
to a bus. A large number of nodes requires a transceiver with high input impedance such as the HVD233.

SLLS557D − NOVEMBER 2002 REVISED JUNE 2005
The standard specifies the interconnect to be a single twisted-pair cable (shielded or unshielded) with 120-Ω
characteristic impedance (ZO). Resistors equal to the characteristic impedance of the line terminate both ends of
the cable to prevent signal reflections. Unterminated drop-lines (stubs) connecting nodes to the bus should be kept
as short as possible to minimize signal reflections.
Slope Control
The rise and fall slope of the SN65HVD233, SN65HVD234, and SN65HVD235 driver output can be adjusted by
connecting a resistor from the Rs (pin 8) to ground (GND), or to a low-level input voltage as shown in Figure 29.
The slope of the driver output signal is proportional to the pin’s output current. This slope control is implemented with
an external resistor value of 10 kΩ to achieve a ≈ 15 V/µs slew rate, and up to 100 kΩ to achieve a ≈ 2.0 V/µs slew
rate as displayed in Figure 30. Typical driver output waveforms with slope control are displayed in Figure 31.

Standby
If a high−level input (> 0.75 VCC) is applied to Rs (pin 8), the circuit enters a low-current, listen only standby mode
during which the driver is switched off and the receiver remains active. The local controller can reverse this low-power
standby mode when the rising edge of a dominant state (bus differential voltage > 900 mV typical) occurs on the bus.
