Cost optimization in car manufacturing is of extreme importance today. Solutions to this problem often implies the use of more advanced and intelligent electronic circuits. The TSS461C is a circuit which allows the transfer of all the status information needed in a car or truck over a single low-cost wire pair, that minimizes the electrical wire usage. It can be used to interconnect powerful functions (ABS, dashboard, power train control) and to control and interface car body electronics (lights, wipers, power window, etc.).
