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 1 Mbit/s.
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 4). Pin TxD is pulled high internally should the
input become disconnected.

ELECTRICAL CHARACTERISTICS
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.
