描述 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 stand-alone CAN 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, extremly low electromagnetic emission (EME) is achieved by the excellent matching of the output signals.
