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 | CLK | input | Clock input. Data at D is transferred to Q on the positive-going edge of CLK when PRE and CLR are inactive (high). Accepts input voltages up to 5.5 V regardless of VCC. |+| 2 | D | input | Data input. Sampled on the rising edge of CLK and transferred to Q when PRE and CLR are inactive high. Input tolerant to 5.5 V. |+| 3 | ~{Q} | output | Complementary (inverted) flip-flop output. Drives ±24 mA at VCC = 3.3 V. Goes high when the internal Q latch is reset by CLR = L. |+| 4 | GND | power_in | Ground reference (0 V) for the device. |+| 5 | Q | output | True flip-flop output. Reflects the state of the D input following the rising edge of CLK. Drives ±24 mA at VCC = 3.3 V. |+| 6 | ~{CLR} | input | Active-low asynchronous clear input. A low level forces Q low regardless of CLK or D. Must be held high for normal clocked operation. |+| 7 | ~{PRE} | input | Active-low asynchronous preset input. A low level forces Q high regardless of CLK or D. Must be held high for normal clocked operation. |+| 8 | VCC | power_in | Positive supply voltage. Operating range 1.65 V to 5.5 V; data retention down to 1.5 V. Bypass locally with a 0.1 µF ceramic capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VSSOP-8 |+| Category | Logic |+| Pins | 8 |++## Ordering variants++- `SN74LVC2G74DCURDCUR`+- `SN74LVC2G74DCURDCUT`+- `SN74LVC2G74DCURDCTR`+- `SN74LVC2G74DCURDCTT`+- `SN74LVC2G74DCURYZPR`++## CAD (KiCad official)++- Symbol: `SN74LVC2G74DCUR`+- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`+- 3D model: VSSOP-8 (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/sn74lvc2g74dcur.pdf) (18 pp, sha256 `5bb76431d38ce5ae`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
