The BS801B/02B/04B/06B/08B are a range of 1 to 8 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.

* Operating voltage: 2.2V~5.5V
* Ultra low standby current: 1.5Aat3V
* Auto-calibration
* High reliability touch detections
* High PSRR
