NV73490 NV73493 ALYW ALYW NCV7349 High Speed Low Power CAN Transceiver Description The NCV7349 CAN transceiver is the interface between a controller area network (CAN) protocol controller and the physical www.onsemi.com bus. The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller. MARKING The NCV7349 is a new addition to the CAN highspeed transceiver DIAGRAM family complementing NCV734x CAN family and previous generations 8 of CAN transceivers such as AMIS42665, AMIS3066x, etc. 8 Due to the wide commonmode voltage range of the receiver inputs NV7349x ALYW and other design features, the NCV7349 is able to reach outstanding 1 levels of electromagnetic susceptibility (EMS). Similarly, very low SOIC8 CASE 751AZ electromagnetic emission (EME) is achieved by the excellent 1 matching of the output signals.
