NCV7342
High Speed Low Power CAN
Transceiver
Description
The NCV7342 CAN transceiver is the interface between a
controller area network (CAN) protocol controller and the physical
bus and may be used in both 12 V and 24 V systems. The transceiver
provides differential transmit capability to the bus and differential
receive capability to the CAN controller.
The NCV7342 is an addition to the CAN high−speed transceiver
family complementing NCV734x CAN stand−alone transceivers and
previous generations such as AMIS42665, AMIS3066x, etc.
Due to the wide common−mode voltage range of the receiver inputs
and other design features, the NCV7342 is able to reach outstanding
levels of electromagnetic susceptibility (EMS). Similarly, extremely
low electromagnetic emission (EME) is achieved by the excellent
matching of the output signals.
