Automotive ICs Single LIN Transceiver TH8080 Bus ICs Because of its very low current consumption in recessive state TH8080 is suitable for ECU applications that have stringent standby current requirements, whereby no sleep/wake up control from the microprocessor is necessary. Intelligent Drivers and Actuators Conform to LIN Protocol Specification Rev. 1.3, 2.0 and SAE J2602 RF & RFID The TH8080 is a physical layer device for a single wire data link. It is capable of operating in applications where no high data rates are required and lower data rates can generate cost reductions both in the physical media components and in the microprocessor which use the network.
