FlexRay® Bus Driver

NCV7381 is a single−channel FlexRay bus driver compliant with the FlexRay Electrical Physical Layer Specification Rev. 3.0.1, capable of communicating at speeds of up to 10 Mbit/s. It provides differential transmit and receive capability between a wired FlexRay communication medium on one side and a protocol controller and a host on the other side.
NCV7381 mode control functionality is optimized for nodes permanently connected to car battery.
It offers excellent EMC and ESD performance.
