ELM334 - Garage Doorman

Datasheet Summary

Description

The ELM334 is an integrated circuit for remotely monitoring the position of electrical contacts (on a garage door, for example) and reporting the position by way of coloured LEDs.

Features

  • Low power CMOS design.
  • Wide supply range - 3.0 to 5.5 volt operation.
  • Simultaneous monitoring of three inputs.
  • Fully debounced inputs.
  • Two wire interface to LEDs.
  • Stuck button protection on the control output.

ELM334 Garage Doorman Description The ELM334 is an integrated circuit for remotely monitoring the position of electrical contacts (on a garage door, for example) and reporting the position by way of coloured LEDs. A two-wire interface is all that is needed to convey the position of the door to two remotely located LEDs, and to also provide pushbutton control for an electric opener if desired. This circuit is able to monitor the state of one or two position sensing switches, provide debouncing of the signals, and to generate an alternating (flashing) output when the position changes. In addition, there is a separate pushbutton input that may be used to control an electric garage door opener, or possibly trigger an alarm.
