DESCRIPTION
The SN65HVD230Q, SN65HVD231Q, and SN65HVD232Q controller area network (CAN) transceivers are
designed for use with the Texas Instruments TMS320Lx240x 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 SN65HVD230Q and SN65HVD231Q, R
(pin 8) provides three different modes of operation:
S
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 SN65HVD230Q 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
(pin 8). The DSP controller reverses this
S
low-current standby mode when a dominant state (bus differential voltage > 900 mV typical) occurs on the bus.
The unique difference between the SN65HVD230Q and the SN65HVD231Q is that both the driver and the
receiver are switched off in the SN65HVD231Q when a high logic level is applied to R
this sleep mode until the circuit is reactivated by a low logic level on R
The V
(pin 5 on the SN65HVD230Q and SN65HVD231Q) is available as a VCC/2 voltage reference.

The SN65HVD232Q is a basic CAN transceiver with no added options; pins 5 and 8 are NC, no connection.
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
