Operating voltage range: 3.3V – 5.5V
Operating current: 3mA (normal mode); 15 uA (sleep mode) @5V
8 touch sensitive buttons
No button for 4 seconds, enter sleep mode
Provide binary (BCD) coded direct output interface (power on D2~D0/111)
After leaving the button, the output state will remain unchanged until the next button.
The button is provided to recognize the effective output. When there is a button, the output is low, and the no button is high.
The sensitivity can be adjusted by adjusting the external capacitor of the CAP pin. The higher the capacitance, the higher the sensitivity.
Waterproof and water-filled water droplets are covered on the touch button panel, and the buttons can still be effectively distinguished.
Built-in LDO increases the immunity of the power supply.
