NCV7446 Dual CAN FD Transceiver, High Speed, Low Power NCV7446 Description NCV7446 is a dual CAN FD physical layer transceiver. It allows interfacing of two independent CAN physical buses and two www.onsemi.com independent CAN protocol controllers. The transceivers provide differential transmit capability to the bus and differential receive capability to the CAN controllers. MARKING It is consisted of two fully independent NCV7344 transceivers. The DIAGRAM NCV7446 guarantees additional timing parameters to ensure robust communication at data rates beyond 1 Mbps to cope with CAN NV74 flexible data rate requirements (CAN FD). These features make the 460 NCV7446 an excellent choice for all types of HSCAN networks, in 1 ALYW DFNW14 nodes that require a lowpower mode with wakeup capability via the CASE 507AC CAN bus.
