Transceiver,
Clamp 30
NCV7381 is a singlechannel 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.
