DATA SHEET www.onsemi.com MARKING High Speed Low Power DIAGRAM CAN, CAN FD Transceiver 8 8 NV7344xy 1 NCV7344 ALYW SOIC8 NB CASE 75107 Description 1 The NCV7344 CAN transceiver is the interface between a controller area network (CAN) protocol controller and the physical bus. The transceiver provides differential transmit capability to the bus 1 1 NV7344xy and differential receive capability to the CAN controller. DFN8 ALYW The NCV7344 is an addition to the CAN highspeed transceiver MW SUFFIX CASE 507AB family complementing NCV734x CAN standalone transceivers and previous generations such as AMIS42665, AMIS3066x, etc. The NCV7344 guarantees additional timing parameters to ensure NV7344xy= Specific Device Code robust communication at data rates beyond 1 Mbps to cope with CAN x = or A flexible data rate requirements (CAN FD). These features make the y = 0 or 3 NCV7344 an excellent choice for all types of HSCAN networks, in = long filter time A = short filter time nodes that require a lowpower mode with wakeup capability via the A = Assembly Location CAN bus.
