SN74AUP1G126DCKR from Texas Instruments, 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, active high; the output is disabled when OE is low, and OE should be tied to GND through a pulldown resistor to assure high-impedance during power up or power down. |
| 2 | A | input | Data input; the input has an input-disable feature that allows floating input signals and is 3.6-V I/O tolerant. |
| 3 | GND | power_in | Ground reference for the device. |
| 4 | Y | tri_state | Buffered 3-state output that is disabled when OE is low; continuous output current is limited to ±20 mA. |
| 5 | VCC | power_in | Positive supply, specified for 0.8 V to 3.6 V operation. |
