General Description
The TH8082 is a physical layer device for a single wire data link capable of operating in applications where high data rate is not required and a lower data rate can achieve cost reductions in both the physical media components and in the microprocessor which use the network. The TH8082 is designed in accordance to the physical layer definition of the LIN Protocol Specification, Rev. 1.3 and 2.0.The IC furthermore can be used in ISO9141 systems.
