500 kBaud. 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 kBaud the ASC terminal is open or tied to GND. For slower speed operation at 125 kBaud 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 SN75LBC031 is characterized for operation from –40°C to 85°C. The SN65LBC031 is characterized for
operation from –40°C to 125°C. The SN65LBC031Q is characterized for operation over the automotive
temperature range of – 40°C to 125°C.
