Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.

FUNCTIONAL DESCRIPTION
AMIS42665 provides two modes of operation as illustrated in Table
5. These modes are selectable through pin STB.

Normal Mode
In the normal mode, the transceiver 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 lines outputs are optimized to
give extremely low EME.
Standby Mode
In standby mode both the transmitter and receiver are
disabled and a very lowpower differential receiver
monitors the bus lines for CAN bus activity. The bus lines
are terminated to ground and supply current is reduced to a
minimum, typically 10
mA. When a wakeup request is
