SN74LVC1GX04DCKR from Texas Instruments, in a SC-70-6. 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 static level; not internally bonded. |
| 2 | GND | power_in | Ground reference (0 V) for the device. Connect to the system ground plane. |
| 3 | X1 | input | Amplifier input of the unbuffered inverter (LVC1GU04 portion). Connect to one terminal of the crystal/resonator through the oscillator load network (Rf ≈ 2.2 MΩ, C1 ≈ 32 pF typical). Input capacitance Ci ≈ 7 pF at 3.3 V. |
| 4 | X2 | output | Amplifier output of the unbuffered inverter. Connect to the second crystal terminal through the load network (Rs ≈ 1 kΩ, C2 ≈ 32 pF typical). Feeds the internal buffer chain that drives Y. |
| 5 | VCC | power_in | Positive supply voltage, 1.65 V to 5.5 V operating (1.5 V data retention; 2 V minimum for crystal oscillator use). Bypass locally with a decoupling capacitor to GND. ICC ≤ 10 µA. |
| 6 | Y | output | Main buffered square-wave clock output driven by the LVC1G04 buffer chain. Rail-to-rail CMOS drive with ±24 mA capability at 3.3 V; supports partial-power-down (Ioff) for hot-insertion / power-sequencing applications. |
