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 | A | input | Logic input A of the 2-input NOR gate. CMOS Schmitt-trigger input; VIH = 2.1 V at VCC = 3 V, VIL = 0.9 V at VCC = 3 V. Must not be left floating; tie to VCC or GND if unused. |+| 2 | B | input | Logic input B of the 2-input NOR gate. CMOS Schmitt-trigger input identical to input A. Must not be left floating; tie to VCC or GND if unused. |+| 3 | GND | power_in | Device ground reference (0 V). Connect to system ground with a low-impedance path and decouple VCC to this pin. |+| 4 | Y | output | NOR gate output, Y = NOT(A OR B). Push-pull CMOS output rated ±8 mA at VCC = 5 V (±4 mA at 3.3 V). Swings rail-to-rail between GND and VCC. |+| 5 | VCC | power_in | Positive supply voltage, 2 V to 5.5 V recommended (7 V absolute max). Bypass with a 0.1-µF ceramic capacitor to GND close to the pin. Quiescent supply current ICC ≤ 10 µA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | Logic |+| Pins | 5 |++## Ordering variants++- `SN74AHC1G02DBVRDBVR`+- `SN74AHC1G02DBVRDBVT`+- `SN74AHC1G02DBVRDCKR`+- `SN74AHC1G02DBVRDCKT`+- `SN74AHC1G02DBVRDRLR`++## CAD (KiCad official)++- Symbol: `SN74AHC1G02DBVR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/sn74ahc1g02.pdf) (26 pp, sha256 `99cfc4da49faf337`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
