CAN Bus Drivers |

The CAN bus driver adapts the signals from the CAN controller, which usually uses ordinary TTL levels, to the physical layer used. AMI
Semiconductors: AMIS-30660 CAN transceivers, ISO11898-2 compatible. Several models with different features. Infineon: TLE6250G82C251-type, for 12 or 24V systems. Version for both 5 and 3.3V. P-DSO-8-3 package. Infineon: TLE6252GSimilar to the TJA1053 from Philips. Switches to single-wire mode during bus line failure events. Supports one-wire transmission mode with ground offset voltages up to 1.5V. Low-power sleep mode. Packaged in P-DSO-14-2. Infineon: TLE6255GSingle-Wire up to 40kbit/s. -40 to +125 Celsius operating temp. Vcc range 5.5 to 28V. Low power sleep mode. Programmable bus out slew rate. 100kbit/s diagnostic mode. P-DSO-14-4 package. Philips: PCA82C250A very common driver chip. Implements the ISO 11898-2 physical layer. May be used with bus speeds up to 1 Mb/s. Available in DIL-8 and SO-8 packages. PDF-data sheet Philips: 82C251Almost as the 82C250 but tolerates higher voltages - up to 28V, which makes it especially suited for trucks and bus (note the pun!) applications. PDF- data sheet Philips: PCA82C252A "low-speed CAN" (ISO11898-3) transceiver. Magnificent fault tolerance and fault detection. 24V-tolerant. Supports one-wire transmission. Available in SO-14 package. PDF-data sheet High-speed (ISO11898-2) transceiver comparable to the TJA1050, but with the following differences: An ideal passive behaviour when supply voltage is off; A very low-current standby mode with remote wake-up capability via the bus. High-speed (ISO11898-2) transceiver featuring low-power management, supporting local and remote wake-up with wake-up source recognition and the capability to control the power supply in the rest of the node; Several protection and diagnosis functions including short circuits of the bus lines and first battery connection; Automatic adaptation of the I/O-levels, in line with the supply voltage of the controller. High-speed (ISO11898-2) transceiver comparable to the 82C251, but with the following differences: Much lower electromagnetic emission due to optimal matching of the output signals CANH and CANL; Improved behaviour in case of an unpowered node; No standby mode. Very similar to 82C252 (that is, these are low-speed fault-tolerant transceivers that follow ISO11898-3) but is better prepared to handle systems with more than 15 nodes. There is also a timer to prevent outputting a permanent dominant level. A Single-Wire CAN (SWC) transceiver. Vishay Siliconix: Si9200EYImplements ISO11898-2, compatible with 82C250. Available in SO-8. Temic: B10011SCAN bus interface chip. SO-16 package. Intended for low speed, high signal levels applications like trucks. Texas: SN75LBC031Meets ISO 11898-2. Up to 500 kbit/s. Available in DIP-8 and SO-8. Temperature range -40 + +85 °C. Also available as SN65LBC031 with the full automotive temperature range -40 - +125 °C. Texas:
SN65HVD232, 3.3-V Can Transceiver
