NCV7344/D
NCV7344
High Speed Low Power
CAN, CAN FD Transceiver
Description
The NCV7344 CAN transceiver is the interface between a
controller area network (CAN) protocol controller and the physical
bus. The transceiver provides differential transmit capability to the bus
and differential receive capability to the CAN controller.
The NCV7344 is an addition to the CAN high−speed transceiver
family complementing NCV734x CAN stand−alone transceivers and
previous generations such as AMIS42665, AMIS3066x, etc.
The NCV7344 guarantees additional timing parameters to ensure
robust communication at data rates beyond 1 Mbps to cope with CAN
flexible data rate requirements (CAN FD). These features make the
NCV7344 an excellent choice for all types of HS−CAN networks, in
nodes that require a low−power mode with wake−up capability via the
CAN bus.
