SN74AHCT1G125DBVR

UMW · Gates · SOT-23-5

SN74AHCT1G125DBVR 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	OE	input	Active-low output enable (OE, overlined). When low, the buffer passes A to Y; when high, Y is placed in the high-impedance (Hi-Z) 3-state. TTL-compatible input.
2	A	input	Buffer data input. TTL-voltage compatible (VIH ≥ 2 V, VIL ≤ 0.8 V). Passed to output Y when OE is low.
3	GND	power_in	Device ground reference (0 V).
4	Y	tri_state	Buffer 3-state output. Drives ±8 mA at 5 V; follows A when OE is low, Hi-Z when OE is high.
5	VCC	power_in	Positive supply voltage. Recommended operating range 4.5 V to 5.5 V; absolute max 7.0 V. Bypass with a 100 nF ceramic capacitor close to the pin.

CAD (KiCad official)

Symbol: SN74AHCT1G125DBVR
Footprint: Package_TO_SOT_SMD:SOT-23-5
3D model: SOT-23-5 (KiCad packages3D, STEP)
3D model files: sn74ahct1g125dbvr-etched.step / sn74ahct1g125dbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74ahct1g125dbvr.step / sn74ahct1g125dbvr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74ahct1g125dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74ahct1g125dbvr-etched.step`	2.4 MB	You want the part with `SN74AHCT1G125DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 623 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 (10 pp, sha256 72ab42624be87c31, retrieved 2026-08-17, tier: lcsc)
Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
