SN74LVC1G14DBVR

UMW · Inverters · SOT-23-5

SN74LVC1G14DBVR from UMW, in a SOT-23-5. 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 NC unconnected No connect. Empty foot, no internal bond wire. Leave floating or tie to any convenient net for mechanical soldering only.
2 A input Schmitt-trigger logic input. Threshold VT+/VT- scale with VCC (e.g. VT+ 2.16-2.74 V and VT- 1.41-1.79 V at VCC = 4.5 V; hysteresis ~0.71-1.04 V). Input voltage range 0 to 5.5 V, input leakage ~0.01 µA typical (±5 µA max).
3 GND power_in Ground / power supply return (0 V).
4 Y output Inverted CMOS logic output (Y = /A). Rail-to-rail push-pull drive; sinks/sources up to 32 mA at VCC = 4.5 V (16 mA @ 3 V, 8 mA @ 2.3 V, 4 mA @ 1.65 V). Typical propagation delay ~20 ns with CL = 15 pF at VCC = 5.0 V.
5 VCC power_in Positive supply. Operating range 1.65 V to 5.5 V (abs-max 6.5 V). Quiescent current ~0.1 µA typical (10 µA max). Decouple locally with a 0.1 µF capacitor to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74lvc1g14dbvr.step 85 KB You want the bare part, or you mark your own boards.
sn74lvc1g14dbvr-etched.step 2.0 MB You want the part with SN74LVC1G14DBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 535 faces against 102 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: UMW datasheet (15 pp, sha256 805e99b1847f2f40, retrieved 2026-08-17, tier: lcsc)
  • 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).
