SN74LVC1G74DCUR

Texas Instruments · Flip Flops · VSSOP-8

SN74LVC1G74DCUR from Texas Instruments, in a VSSOP-8. 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 the D input is transferred to Q on the positive (rising) edge of CLK, provided setup/hold requirements are met.
2 D input Data input to the D-type flip-flop. Logic level present at D is captured to Q on the rising edge of CLK.
3 ~{Q} output Inverted (complementary) flip-flop output. Drives ±24 mA at VCC = 3.3 V.
4 GND power_in Ground reference (0 V) for the device.
5 Q output Non-inverted flip-flop output. Drives ±24 mA at VCC = 3.3 V.
6 ~{CLR} input Active-low asynchronous clear input. Pull low to force Q low (and ~{Q} high) regardless of CLK/D. Must be held high (inactive) for normal clocked operation.
7 ~{PRE} input Active-low asynchronous preset input. Pull low to force Q high (and ~{Q} low) regardless of CLK/D. Must be held high (inactive) for normal clocked operation.
8 VCC power_in Positive supply voltage, 1.65 V to 5.5 V operating range (1.5 V minimum for data retention only).

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74lvc1g74dcur.step 122 KB You want the bare part, or you mark your own boards.
sn74lvc1g74dcur-etched.step 2.5 MB You want the part with SN74LVC1G74DCUR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 622 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (24 pp, sha256 be9952765c368693, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
