General Description
Provides 8 touch keys with binary code (BCD) output and the display of acknowledgment output of key pressing. The data after key pressing will remain
until another key is pressed, which can be used to determine the acknowledgment status of key pressing. It also has excellent performance of waterproof and anti-interference
Features
Operating Voltage: 3.1V - 5.5V
Operating current: 3mA@5V
8 touch control keys
Provides binary coding (BCD) direct output interface (power on D2~D0/111)
If the user leaves the operation after pressing a key, the output state will remain
until another key is pressed
Provides output for acknowledgment of effective key pressing. The output is at
low voltage level when a key is pressed and at high voltage level when no key is
pressed
Sensitivity is adjustable through adjustment of the external capacitor connected
to CAP pin. Sensitivity is higher with larger capacitance
Waterproof and immersion proof. Key function is still effective even with water
droplets covering the touch key panel
The built-in LDO enhances the anti-interference capability of power supply
Applications
Various types of small and large appliances and entertainment products
