The SN65HVD233-Q1, SN65HVD234-Q1, and SN65HVD235-Q1 devices are fault-protected 3.3-V CAN transceivers that are qualified for use in automotive applications. These transceivers work from a 3.3-V supply and are ideal for systems that also leverage a 3.3-V microcontroller, thereby reducing the need for additional components or a separate supply to power the controller and the CAN transceiver. The SN65HVD23x-Q1 transceivers are compatible with the ISO 11898-2 standard and thus are interoperable in mixed networks that employ 5-V CAN and/or 3.3-V CAN transceivers.

Designed for operation in especially harsh environments, the devices feature crosswire protection, overvoltage protection on the CANH and CANL pins up to ±36 V, loss-of-ground protection, overtemperature (thermal shutdown) protection, and common-mode transient protection of ±100 V. These devices operate over a wide –7-V to 12-V common-mode range. These transceivers are the interface between the host CAN controller on the microprocessor and the differential CAN bus used in transportation and automotive applications.

Modes:The RS pin (pin 8) of the SN65HVD233-Q1, SN65HVD234-Q1, and SN65HVD235-Q1 devices provides three modes of operation: high-speed, slope control, and 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 between the RS pin and ground. The slope is proportional to the output current of the pin. With a resistor value of 10 kΩ the device driver has a slew rate of approximately 15 V/µs, and with a value of 100 kΩ the device has a slew rate of approximately 2 V/µs.
