description

The SN75LBC031 is a CAN transceiver used as

an interface between a CAN controller and the

physical bus for high speed applications of up to

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

. 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.
