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 | Push-pull touch detection output. Polarity (active-high or active-low) is set by SLH; behavior (direct/toggle) is set by STG. Sink capability IOL=10mA at VOL=0.6V, source capability IOH=-6mA at VOH=2.4V (VDD=3V). Max response time 60ms. |+| 2 | GND | power_in | Power ground (VSS reference). |+| 3 | SO | input | Touch sensor input. Connects to the external touch sensing pad, typically through an optional 100-1000Ω series resistor (Rs) for improved EMI immunity. Sensitivity is set by an external capacitor (C1, 0-50pF) from this pin to GND - larger C = lower sensitivity. |+| 4 | SLH | input | Output active-level select. Tie to GND → OUT is active-high on touch (idle low); tie to VDD → OUT is active-low on touch (idle high). Must NOT be left floating. |+| 5 | VDD | power_in | Positive supply, 2.0V to 5.5V (typ 3.0V). Typical operating current 2.5uA (max 7uA) at VDD=3.0V. Onboard LDO provides internal regulation. |+| 6 | STG | input | Mode select strap. Tie to GND → direct/synchronous output mode (OUT follows touch, like a momentary key); tie to VDD → toggle/latched mode (OUT flips state on each touch, like a self-locking switch). Max continuous touch time 6s in either mode. Must NOT be left floating. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TDSEMIC |+| Package | SOT-23-6 |+| Category | Sensor |+| Pins | 6 |++## Ordering variants++- `TTP223-TDTD`++## CAD (KiCad official)++- Symbol: `TTP223-TD`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TDSEMIC datasheet](docs/ttp223-td-datasheet.pdf) (6 pp, sha256 `62ca6bb632f6de27`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
