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 | A1 | input | Schmitt-trigger input to inverter 1. VT+ typ 2.7 V, VT- typ 1.8 V at VCC = 4.5 V; hysteresis typ 0.9 V. Max input current ±1 µA. |+| 2 | Y1 | output | Inverted Schmitt-trigger output of gate 1 (Y1 = !A1). Drives ±4 mA at VCC = 4.5 V (VOH ≥ 3.98 V, VOL ≤ 0.26 V). |+| 3 | A2 | input | Schmitt-trigger input to inverter 2. Same thresholds and hysteresis as A1. |+| 4 | Y2 | output | Inverted Schmitt-trigger output of gate 2 (Y2 = !A2). |+| 5 | A3 | input | Schmitt-trigger input to inverter 3. |+| 6 | Y3 | output | Inverted Schmitt-trigger output of gate 3 (Y3 = !A3). |+| 7 | GND | power_in | Ground reference (0 V). Common return for VCC. |+| 8 | Y4 | output | Inverted Schmitt-trigger output of gate 4 (Y4 = !A4). |+| 9 | A4 | input | Schmitt-trigger input to inverter 4. |+| 10 | Y5 | output | Inverted Schmitt-trigger output of gate 5 (Y5 = !A5). |+| 11 | A5 | input | Schmitt-trigger input to inverter 5. |+| 12 | Y6 | output | Inverted Schmitt-trigger output of gate 6 (Y6 = !A6). |+| 13 | A6 | input | Schmitt-trigger input to inverter 6. |+| 14 | VCC | power_in | Positive supply. Recommended 2 V to 6 V; absolute max 7.0 V. Quiescent supply current typ 2 µA (max 20 µA at 25 °C). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | TSSOP-14 |+| Category | Logic |+| Pins | 14 |++## Ordering variants++Same part, different packaging or reel option.++- `MM74HC14MTCX`+- `MM74HC14MTCXM`+- `MM74HC14MTCXSJ`+- `MM74HC14MTCXN`++## CAD (KiCad official)++- Symbol: `MM74HC14MTCX`+- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`+- 3D model: TSSOP-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/mm74hc14mtcx-d.pdf) (10 pp, sha256 `e3bbc5909972bfbd`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
