NCV7383 FlexRay Transceiver, Clamp 15 NCV7383 is a singlechannel FlexRay bus driver compliant with the FlexRay Electrical Physical Layer Specification Rev. 3.0.1, www.onsemi.com capable of communicating at speeds of up to 10 Mbit/s. It provides differential transmit and receive capability between a wired FlexRay MARKING communication medium on one side and a protocol controller and DIAGRAM a host on the other side. NCV7383 mode control functionality is optimized for nodes 14 14 without the need of extended power management provided by NV73 transceivers with permanent connection to the car battery as is on 830 1 ALYW NCV7381. NCV7383 is primarily intended for nodes switched off by TSSOP14 ignition. CASE 948G 1 It offers excellent Electromagnetic compatibility (EMC) and Electrostatic discharge (ESD) performance.
