NCV7422 LIN Transceiver, Dual NCV7422 Description The NCV7422 is a two channel physical layer device using the Local Interconnect Network (LIN) protocol. It allows interfacing of two independent LIN physical buses and the LIN protocol controllers. The device is compliant to ISO 179874, LIN2.2a, LIN2.2, LIN2.1, www.onsemi.com LIN 2.0 and SAEJ2602 standards. The NCV7422 LIN device is a member of the in vehicle networking (IVN) transceiver family. MARKING The LIN bus is designed to communicate lowrate data from control DIAGRAM devices such as door locks, mirrors, car seats and sunroofs at the lowest possible cost. The bus is designed to eliminate as much wiring 1 as possible and is implemented using a single wire in each node. Each NV74 DFN14 220 node has a slave MCUstate machine that recognizes and translates MW SUFFIX ALYW the instructions specific to that function. CASE 507AC The main attraction of the LIN bus is that all the functions are not time critical and usually relate to passenger comfort.
