This datasheet also covers the TTP224 variant, as both devices belong to the same 4 key touch pad detector ic family and are provided as variant models within a single manufacturer datasheet.
Key Features
Operating voltage 2.4V~5.5V Built-in regulator with external enable/disable option Operating current, @VDD=3V no load At low power mode typical 2.5uA At fast mode typical 9.0uA @VDD=3V operating voltage : The response time about 100mS at fast mode, 200mS at low power mode for TTP224 The response time about 60mS at fast mode, 160mS at low power mode for TTP224N Sensitivity can adjust by the capacitance(0~50pF) outside for each tou.

s capacitive sensing design specifically for touch pad controls. The device built in regulator for touch sensor. Stable sensing method can cover diversity conditions. Human interfaces control panel links through non-conductive dielectric material. The main application is focused at replacing of the mechanical switch or button. The ASSP can independently handle the 4 touch pads with 4 direct output pins. GENERAL DESCRIPTION FEATURES Operating voltage 2.4V~5.5V Built-in regulator with external enable/disable option Operating current, @VDD=3V no load At low power mode typical 2.5uA At fast mode typical 9
