SN74AUP1G34DBVR

Texas Instruments · Buffer/Driver/Transceiver · SOT-23-5

SN74AUP1G34DBVR from Texas Instruments, 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 internal connection. Leave floating or tie to a stable potential per board practice; the pin has no electrical function.
2 A input Logic input A for the non-inverting buffer. CMOS input with hysteresis (Vhys ≈ 250 mV typ at 3.3 V); accepts 0 V to 3.6 V regardless of VCC (3.6-V input tolerant). Input capacitance Ci ≈ 1.5 pF typ.
3 GND power_in Ground reference (0 V). Return for VCC and all logic signals.
4 Y output Buffered logic output Y = A. Push-pull CMOS output; drive strength scales with VCC (e.g., IOH/IOL ≈ ±4 mA at VCC = 3 V, ±1.9 mA at 1.65 V). Supports live insertion, partial power-down (Ioff), and back-drive protection.
5 VCC power_in Positive supply pin. Recommended operating range 0.8 V to 3.6 V (absolute max 4.6 V). Bypass locally with a small ceramic (e.g., 0.1 µF) to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74aup1g34dbvr.step 85 KB You want the bare part, or you mark your own boards.
sn74aup1g34dbvr-etched.step 2.4 MB You want the part with SN74AUP1G34DBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 609 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: Texas Instruments datasheet (46 pp, sha256 5454c44394b2cc30, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
