**TECH PUBLIC** · Buffers, Drivers, Receivers, Transceivers · SOT-353

SN74LVC1G34DCKR-TP from TECH PUBLIC, 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 | NC | unconnected | No connect pin; the datasheet gives no function or limits for it. |
| 2 | A | input | Buffer input (Y = A) that accepts voltages up to 5.5V, with an absolute maximum input voltage of -0.5 to +6.5V. |
| 3 | GND | power_in | Ground pin for the device. |
| 4 | Y | output | Buffer output that follows input A, with absolute maximum output voltage of -0.5 to VCC+0.5V in the high or low state and continuous output current of ±50mA. |
| 5 | VCC | power_in | Supply pin, operating range 1.65V to 5.5V with an absolute maximum of -0.5 to +6.5V. |

## CAD (KiCad official)

- Symbol: `SN74LVC1G34DCKR-TP`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SOT-353 (KiCad packages3D, STEP)
- 3D model files: `sn74lvc1g34dckr-tp-etched.step` / `sn74lvc1g34dckr-tp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sn74lvc1g34dckr-tp.step` / `sn74lvc1g34dckr-tp.glb` are the bare package body.
