AMIS-42671 High-Speed CAN Transceiver
Data Sheet
For Long Networks
7.3 High Communication Speed Range
The transceiver is primarily intended for industrial applications. It allows very low baud rates needed for long bus length applications.
But also high speed communication is possible up to 1Mbit/s.
7.4 Fail-safe Features
A current-limiting circuit protects the transmitter output stage from damage caused by an accidental short-circuit to either positive or
negative supply voltage, although power dissipation increases during this fault condition.
The pins CANH and CANL are protected from automotive electrical transients (according to “ISO 7637”; see Figure 5). Pin TxD is
pulled high internally should the input become disconnected.
8.0 Electrical Characteristics
8.1 Definitions
All voltages are referenced to GND (pin 2). Positive currents flow into the IC. Sinking current means the current is flowing into the pin;
sourcing current means the current is flowing out of the pin.
8.2 Absolute Maximum Ratings
Stresses above those listed in the following table may cause permanent device failure. Exposure to absolute maximum ratings for
extended periods may affect device reliability.
