Overview
The NCV7340D12R2G is a high-speed, low-power CAN (Controller Area Network) transceiver produced by ON Semiconductor. It serves as the interface between a CAN protocol controller and the physical bus, making it suitable for both 12 V and 24 V systems. This transceiver is designed to provide differential transmit capability to the bus and differential receive capability to the CAN controller. It is an improved drop-in replacement for the AMIS-42665 and is AEC-Q100 qualified, making it ideal for automotive and industrial applications.
