74LVC1G126CT05ARCQ from GR, in a SC-70-5. 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: when OE is low the output Y is disabled (high impedance), and when OE is high the output follows A. |
| 2 | A | input | Data input of the buffer; the datasheet states inputs accept voltages up to 5.5 V. |
| 3 | GND | power_in | Ground reference, 0 V, to which all voltages are referenced. |
| 4 | Y | output | 3-state buffer output with ±24 mA drive at 3.3 V VCC, high impedance when OE is low. |
| 5 | VCC | power_in | Supply voltage for 1.65 V to 3.6 V operation; the datasheet also states 5 V VCC operation is supported. |
