Overview
The NCV7340D13R2G is a high-speed, low-power CAN (Controller Area Network) transceiver produced by onsemi. This component serves as the interface between a CAN protocol controller and the physical bus, supporting both 12 V and 24 V systems. It is designed to be an improved drop-in replacement for the AMIS-42665 and is compatible with the ISO 11898 standard (ISO 11898-2, ISO 11898-5, and SAE J2284). The NCV7340D13R2G features low quiescent current, high-speed data transmission up to 1 Mbps, and excellent electromagnetic susceptibility (EMS) and electromagnetic emission (EME) performance.
