The NCV7340 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 NCV7340 is a new addition to the CAN high-speed transceiver family and is an improved drop-in replacement for the AMIS-42665 (AMIS42665TJAA1RG).
Due to the wide common-mode voltage range of the receiver inputs, the NCV7340 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.
