**XBLW** · Buffers, Drivers, Receivers, Transceivers · SOT-353

SN74LVC1G126T353 from XBLW, in a SOT-353. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OE | input | Output enable input; the output Y is high-impedance (Z) when OE is low and follows A when OE is high. |
| 2 | A | input | Data input; inputs are overvoltage tolerant to 5.5 V and have Schmitt-trigger action. |
| 3 | GND | power_in | Ground (0 V). |
| 4 | Y | tri_state | Data output with 3-state capability, ±24 mA output drive at VCC = 3.0 V. |
| 5 | VCC | power_in | Supply voltage, 1.65 V to 5.5 V operating range. |

## CAD (KiCad official)

- Symbol: `SN74LVC1G126T353`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SOT-353 (KiCad packages3D, STEP)
- 3D model files: `sn74lvc1g126t353-etched.step` / `sn74lvc1g126t353-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sn74lvc1g126t353.step` / `sn74lvc1g126t353.glb` are the bare package body.
