This device has 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. This transceiver interfaces the single-ended CAN controller with the differential CAN bus
found in industrial, building automation, and automotive applications.
The R
S
(pin 8) of the SN65HVD233 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 R
S
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 R
S
, 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 ≈ 15 V/ µ s and a value of 100 k Ω to achieve ≈ 2.0 V/ µ s slew rate. For more information about slope
control, refer to the application information section.
The SN65HVD233 enters 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 R
S
. 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.
