General Description
The TH8080 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 com-
ponents and in the microprocessor which use the net-
work. The TH8080 is designed in accordance to the
physical layer definition of the LIN Protocol Specifica-
tion , Rev. 1.1 . The IC furthermore can be used in
ISO9141 systems.
Because of the very low current consumption of the
TH8080 in the recessive state it’s particularly suitable for
ECU applications with hard standby current require-
ments , whereby no sleep/wake up control due to the
microprocessor is necessary.
