AI01K sot23-6 from Sam wing, in a SOT-23-6. 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 OUT output Key sense value output. Behavior depends on MD pin: MD=floating → open-drain active-low (requires external pull-up); MD=VDD → push-pull active-high direct output; MD=GND → toggle/self-latch output starting low, inverting on each press. Isk = 10 mA @ VCC=5V, low-level output impedance ≈ 50 Ω, high-Z impedance ≈ 100 MΩ.
2 GND power_in Ground / negative supply reference (0 V).
3 KEY input Touch sense input pin. Connects to the touch pad (sense antenna) through a series resistor (RX ≈ 2 kΩ typical, range 0-5 kΩ). Minimum detectable capacitance change ≈ 0.2 pF.
4 MD input Output-mode select input. Three states: floating → OUT is active-low open-drain (needs external pull-up); tied to VDD → OUT is active-high push-pull direct output; tied to GND → OUT is toggle/self-latch mode starting low.
5 VDD power_in Positive supply input. Operating range 2.5 V to 6.5 V. Typical Idd = 1.6 mA @ 5.0 V, 0.8 mA @ 3.0 V. Decouple with 100 nF close to pin plus a 20 Ω series resistor from the rail as shown in the reference schematic.
6 C1 passive Internal reference source output. Requires a 4.7 nF capacitor to GND placed close to the pin. Do not load with anything else.
