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 | 1A | input | Buffer 1 input. CMOS logic input accepting 0 V to 5.5 V regardless of VCC (supports down-translation and live insertion). VIH/VIL scale with VCC (e.g. 0.65×VCC / 0.35×VCC at VCC=1.65-1.95 V). |+| 2 | GND | power_in | Ground reference (0 V) for the device. Continuous current through VCC or GND is limited to ±100 mA absolute maximum. |+| 3 | 2A | input | Buffer 2 input. CMOS logic input accepting 0 V to 5.5 V regardless of VCC. Unused inputs must be tied to VCC or GND to avoid floating CMOS input current. |+| 4 | 2Y | output | Buffer 2 output (Y = A). Push-pull CMOS output rated ±24 mA at VCC = 3 V (up to ±32 mA at VCC = 4.5 V). Placed in high-impedance / Ioff mode when VCC = 0 V. |+| 5 | VCC | power_in | Positive supply pin. Recommended operating range 1.65 V to 5.5 V (data-retention minimum 1.5 V); absolute maximum 6.5 V. Bypass locally with a 0.1 µF ceramic capacitor to GND. |+| 6 | 1Y | output | Buffer 1 output (Y = A). Push-pull CMOS output rated ±24 mA at VCC = 3 V. Ioff circuitry disables the output when the device is powered down. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SC-70-6 |+| Category | Logic |+| Pins | 6 |++## Ordering variants++- `SN74LVC2G34DCKRDCKR`+- `SN74LVC2G34DCKRDCKT`+- `SN74LVC2G34DCKRDBVR`+- `SN74LVC2G34DCKRDBVT`+- `SN74LVC2G34DCKRDRLR`+- `SN74LVC2G34DCKRYZPR`++## CAD (KiCad official)++- Symbol: `SN74LVC2G34DCKR`+- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`+- 3D model: SC-70-6 (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/sn74lvc2g34.pdf) (30 pp, sha256 `faa5171ab00e49fc`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
