**UTC Unisonic Tech** · Gates · SOT-353

U74LVC1G08G from UTC Unisonic Tech, in a SOT-353. 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 | A | input | Logic input A of the 2-input AND gate. CMOS-compatible input tolerant to 5.5 V regardless of VCC; VIH ≥ 0.65×VCC (1.65-1.95 V range) or ≥ 2 V (3.0-3.6 V range), VIL ≤ 0.35×VCC. Input transition rate ≤ 20 ns/V at 1.8/2.5 V, ≤ 10 ns/V at 3.3 V, ≤ 5 ns/V at 5 V. |
| 2 | B | input | Logic input B of the 2-input AND gate. Same CMOS input characteristics as A: 5.5 V tolerant, VIH/VIL scale with VCC per the static-characteristics table. |
| 3 | GND | power_in | Device ground (0 V) reference. Continuous ICC / IGND current is limited to ±100 mA absolute maximum. |
| 4 | Y | output | AND-gate output, Y = A × B. Drives ±24 mA at VCC = 3.0 V (VOH ≥ 2.3 V at −24 mA; VOL ≤ 0.55 V at 24 mA). Continuous output current limited to ±50 mA absolute maximum. Bypass with a local 0.1 µF cap between VCC and GND close to the device. |
| 5 | VCC | power_in | Positive supply. Operating range 1.65 V to 5.5 V (1.5 V data-retention only). Quiescent supply current ICC ≤ 10 µA. Absolute max 6.5 V. Decouple locally with 0.1 µF to GND. |

## CAD (KiCad official)

- Symbol: `U74LVC1G08G`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SOT-353 (KiCad packages3D, STEP)
- 3D model files: `u74lvc1g08g-etched.step` / `u74lvc1g08g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `u74lvc1g08g.step` / `u74lvc1g08g.glb` are the bare package body.
