The device provides transmitting capability to the CAN controller. The transmitter outputs C_H and C_L are protected against short circuits and electrical transients which may occur in an automotive environment. In case of short circuit (C_H to C_L, C_H to B) the protection circuit recognizes this fault condition and the transmitter output stages are disabled with a delay of max. 10 ms to prevent destruction of the IC and high consumption of supply current IS. If VC_L > VC_L max the transmitter output stages would be disabled immediately. Pin ASC makes it possible to select two different modes of operation: high speed (≤ 1 Mbaud) and low speed (≤ 250 kbaud). The ASC pin is tied to GND for normal operation at ≤ 1 Mbaud. For slower speed operation at ≤ 250 kbaud the rise and fall slope of the bus output can be decreased to reduce EMI by connecting the ASC pin to VS. Table 6.
