Multiplexed control of vehicle dashboard functions - saves on wiring and power losses in wires and includes trigger amplifiers and registers

摘要

A multiplexer enables the many functions controlled from vehicle dashboard to be operated with minimum number of wires. This saves on wiring and power losses in wires. A receiving circuit receives signals from multiplexing output circuit via transmission line. Two trigger amplifiers in series supply signals directly to register. Clock information passes via differential input amplifier and inverter to the register. Clock signal is also applied via monostable to memory bistabls connected in parallel to register outputs, bistable outputs are connected via transistor drives circuits to various functions.
