Product Introduction
The SN65HVD230, SN65HVD231, and SN65HVD232 controller area network (CAN) transceivers are designed for use with 3.3-V DSPs with CAN controllers, or with equivalent devices. They are intended for use in applications employing the CAN serial communication physical layer in accordance with the ISO 11898 standard. Each CAN transceiver is designed to provide differential transmit capability to the bus and differential receive capability to a CAN controller at speeds up to 1 Mbps.
Designed for operation in especially-harsh environments, these devices feature cross-wire protection, loss-of-ground and overvoltage protection, overtemperature protection, as well as wide common-mode range.
The transceiver interfaces the single-ended CAN controller with the differential CAN bus found in industrial, building automation, and automotive applications. It operates over a -2-V to 7-V common-mode range on the bus, and it can withstand common-mode transients of ±25 V.
On the SN65HVD230 and SN65HVD231, pin 8 provides three different modes of operation: high-speed, slope control, and low-power modes. The high-speed mode of operation is selected by connecting pin 8 to ground, allowing the transmitter output transistors to switch on and off as fast as possible with no limitation on the rise and fall slopes. The rise and fall slopes can be adjusted by connecting a resistor to ground at pin 8, since the slope is proportional to the pin's output current. This slope control is implemented with external resistor values of 10 kΩ, to achieve a 15-V/μs slew rate, to 100 kΩ, to achieve a 2-V/μs slew rate.
The circuit of the SN65HVD230 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 pin 8. The DSP controller reverses this low-current standby mode when a dominant state (bus differential voltage >900 mV typical) occurs on the bus.
The unique difference between the SN65HVD230 and the SN65HVD231 is that both the driver and the receiver are switched off in the SN65HVD231 when a high logic level is applied to pin 8 and remain in this sleep mode until the circuit is reactivated by a low logic level on pin 8.
The Vref pin 5 on the SN65HVD230 and SN65HVD231 is available as a VCC/2 voltage reference.
The SN65HVD232 is a basic CAN transceiver with no added options; pins 5 and 8 are NC, no connection.

Frequently Asked Questions
What primary supply voltage levels, signaling rates, and node density limits define the SN65HVD230DR transceiver?
The Texas Instruments SN65HVD230DR is a high-speed CAN (Controller Area Network) transceiver designed to operate from a single 3.3 V supply, with a recommended operating range of 3.0 V to 3.6 V. It is compatible with the ISO 11898 high-speed CAN physical layer standard and supports signaling rates of up to 1 Mbps. Its high input impedance allows up to 120 nodes to be connected to a single CAN bus.
Which package type is available for the SN65HVD230DR?
The SN65HVD230DR is supplied in an 8-pin SOIC (D) surface-mount package. This package is intended for standard SOIC PCB assembly and is available under the ordering options listed in the Package Option Addendum. For detailed mechanical dimensions and PCB land-pattern recommendations, refer to the corresponding TI package outline drawing.
How do the slope control pin and low-power standby mode operate on the SN65HVD230DR?
The RS (Pin 8) pin supports three operating modes: high-speed mode, slope-control mode, and low-power standby mode. Connecting RS directly to ground enables maximum switching speed. Connecting a 10 kΩ to 100 kΩ resistor to ground adjusts the output slew rate to reduce electromagnetic interference (EMI). Driving RS to a logic-high level places the device into a low-current standby mode, in which the driver is disabled while the receiver remains active. The standby supply current is typically 370 μA.
