TTP233H-HA6

Tontek Design Tech · Touch Sensors · SOT-23-6L

TTP233H-HA6 from Tontek Design Tech, in a SOT-23-6L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Q output CMOS push-pull output. Sink current 8 mA (VOL=0.6V @ VDD=3V); source current -4 mA (VOH=2.4V @ VDD=3V). Polarity (active-high/low) and mode (direct/toggle) are selected by AHLB and TOG pins.
2 VSS power_in Negative supply / ground reference for the chip.
3 I bidirectional Touch sensor input port. Connects to the touch PAD/electrode; sensitivity can be adjusted by an external capacitor Cs to VSS in the range 1~50 pF (smaller Cs = higher sensitivity).
4 AHLB input Output active-high/active-low select. 0 (default, internal pull-down ~25kΩ) = active-high output on Q; 1 = active-low output. CMOS input with internal pull-down resistor.
5 VDD power_in Positive power supply, 2.4V to 5.5V (typ. 3V). Bypass with a 100 nF (104) capacitor to VSS placed as close to the pins as possible.
6 TOG input Output mode select. 0 (default, internal pull-down ~25kΩ) = direct output (Q follows touch); 1 = toggle/latch output (Q toggles on each touch). CMOS input with internal pull-down resistor.
