Operating Modes
illustrated in Table 5 below. In case the device is powered,
one of two operating modes can be selected through Pin S.
High−Speed Mode
in its high−speed mode and is able to communicate via the
bus lines. The signals are transmitted and received to the
CAN controller via the Pins TxD and RxD. The slopes on the
bus line outputs are optimized to give extremely low
electromagnetic emissions.
Silent Mode
functions continue to operate. The silent mode is selected by
connecting Pin S to V
communication from being blocked, due to a CAN
controller which is out of control.
Overtemperature Detection
by switching off the transmitter if the junction temperature
exceeds a value of approximately 160°C. Because the
transmitter dissipates most of the power, the power
dissipation and temperature of the IC is reduced. All other
IC functions continue to operate. The transmitter off−state
resets when Pin TxD goes high. The thermal protection
