BS814A-2 - Touch Key

Download the BS814A-2 datasheet PDF. This datasheet also covers the BS812A-1 variant, as both devices belong to the same touch key family and are provided as variant models within a single manufacturer datasheet.

General Description

The BS81x is a series of 2~16 key touch key devices which can detect human body contact using external touch pads.

The high level of device integration enable applications to be implemented with a minimum number of external components.

Key Features

  • Operating voltage: 2.2V~5.5V.
  • Low standby current.
  • Auto-calibration.
  • Reliable touch detections.
  • Standby and normal operating modes.
  • Maximum key on duration time detection.
  • Adaptive voltage drop function.
  • Level Hold, selectable active level- low or high.
  • NMOS output with internal pull-high/CMOS- Direct Output.
  • Both serial interface and parallel outputs.
  • Sensitivity adjustment using an ex.
