 Working voltage: 2.4V~5.5V

 Working current: 1.5uA@3V No-load low power consumption mode

 Complete power-on initialization within 0.5s after power-on is stable

 Reliable power-on reset (POR)

 Built-in dithering circuit can effectively prevent misoperation caused by external noise interference

 Provide the longest touch button output time of about 16s

 Environment adaptive function, which can quickly deal with similar application scenarios such as power-on before covering media, touch power-on and so on



Automatic calibration function: the reference value is refreshed every 1s within 8s after power on. If there are touch keys within 8s or there are still no touch keys after 8s

Recalibration cycle is switched to 4s

 High/low level effective output, fast/low power consumption mode can be selected

 CMOS push-pull output: CT8333-F/Q

NMOS open drain output: CT8333-K/QK

 Packaging form: DFN1 * 1-4L/DFN2 * 2-6L/SOT23-6L
