Overview
The NCV7340D14R2G is a single-channel CAN (Controller Area Network) transceiver produced by onsemi. It serves as the interface between a CAN protocol controller and the physical bus, making it suitable for use in both 12 V and 24 V systems. This transceiver is part of the CAN high-speed transceiver family and is designed as an improved drop-in replacement for the AMIS-42665. It offers differential transmit capability to the bus and differential receive capability to the CAN controller, ensuring high electromagnetic susceptibility (EMS) and low electromagnetic emission (EME).
