description

The SN65LBC031Q is a CAN transceiver used as
an interface between a CAN controller and the
physical bus for high speed applications of up to
500 k Baud. The device provides transmit
capability to the differential bus and differential
receive capability to the controller. The transmitter
outputs (CANH and CANL), feature internal
transition regulation to provide controlled
symmetry resulting in low EMI emissions. Both
transmitter outputs are fully protected against battery short circuits and electrical transients that can occur on
the bus lines. In the event of excessive device power dissipation the output drivers are disabled by the thermal
shutdown circuitry at a junction temperature of approximately 160°C. The inclusion of an internal pullup resistor
on the transmitter input ensures a defined output during power up and protocol controller reset. For normal
operation at 500 k Baud the ASC terminal is open or tied to GND. For slower speed operation at 125 k Baud
the bus output transition times can be increased to reduce EMI by connecting the ASC terminal to V

CC

. The

receiver includes an integrated filter that suppresses the signal into pulses less than 30 ns wide.
The SN65LBC031Q is characterized for operation over the automotive temperature range of –40°C to 125°C.

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.
