TTP223 Touch Switch Module

TTP223 Touch Switch Module The input voltage of this module is 2Volts – 5.5 VDC. The response time max is ~ 60mS in fast mode, ~220mS at low power mode @VDD=3V. Sensitivity can adjust by the capacitance(0~50pF). Stable touching detection of the human body for replacing traditional direct switch key. Provides direct mode toggle mode by pad option (TOG pin). After power-on have about 0.5sec stable-time, during the time do not touch the keypad, and the function is disabled.
