NCV7341

High Speed Low Power CAN
Transceiver

The NCV7341 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.

Due to the wide common

mode voltage range of the receiver inputs,

the NCV7341 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.

The NCV7341 is a new addition to the ON Semiconductor CAN

high

speed transceiver family and offers the following additional

features:
