Elmos Input/Output ICs provide economical possibilities to connect switches, buttons or analog signals to a controller or a discrete logic circuit.

By interference suppression and debouncing of the input signals the use of additional software can be avoided and the hardware can be kept simple. Very small quiescent curent consumption, small demand of external components, as well as high flexibility for the various applications are characteristics shown by the Elmos I/O ICs.

The possibility of polling the switches to operating voltage or ground covers a huge area of applications.

Elmos I/O ICs are already used in the following applications (beside others):

  • Steering column switch, operator panels in door, middle and switch consoles, roof operating units, etc.
  • Limit switch for door lock, unlocking device for the hatchback, sliding roof, etc.
