The TSS463B is a circuit that allows the transfer of all the status information needed in a car or truck over a single low-cost wire pair, thereby minimizing electrical wire usage. It can be used to interconnect powerful functions and to control and interface car body electronics (lights, wipers, power window, etc.). The TSS463B is fully compliant with the VAN ISO standard 11519-3. This standard supports a wide range of applications such as low-cost remote controlled switches, typically it is used for lamp control, up to complex, highly autonomous, distributed systems that require fast and secure data transfers. The TSS463B is a microprocessor-interfaced line controller for mid-to-high complexity bus-masters and listeners like dashboard controllers, car stereo or mobile telephone CPUs.
