SN65LBC031, SN65LBC031Q, SN75LBC031 HIGH-SPEED CONTROLLER AREA NETWORK (CAN) TRANSCEIVERS SLRS048A – MAY 1998 – REVISED APRIL 2000 D D D D D D SN75LBC031 Meets Standard ISO/DIS 11898 (up to 500 k Baud) Driver Output Capability at 50 mA Wide Positive and Negative Input/output Bus Voltage Range Bus Outputs Short-Circuit-Protected to Battery Voltage and Ground Thermal Shutdown Available in Q-Temp Automotive – HighRel Automotive Applications – Configuration Control/Print Support – Qualification to Automotive Standards description D PACKAGE (TOP VIEW) TX GND VCC RX 1 8 2 7 3 6 4 5 ASC CANH CANL REF TERMINAL FUNCTIONS TERMINAL DESCRIPTION TX GND VCC Transmitter input Ground Supply voltage RX Receiver output REF Reference output CANL Low side bus output driver The SN75LBC031 is a CAN transceiver used as CANH High side bus output driver an interface between a CAN controller and the ASC Adjustable slope control physical bus for high speed applications of up to 500 kBaud. The device provides transmit FUNCTION TABLE capability to the differential bus and differential CANH CANL BUS STATE RX TX receive capability to the controller. The transmitter L H L Dominant L outputs (CANH and CANL), feature internal High or floating Floating Floating Recessive H transition regulation to provide controlled L = low, H = high 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 VCC. 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.
