74AHCT1G126DCKRG4 from Texas Instruments, in a SC-70-5. 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 | OE | input | Output Enable input; when low output is disabled to high-impedance state |
| 2 | A | input | Data input A; transferred to output Y when OE is high |
| 3 | GND | power_in | Ground pin |
| 4 | Y | tri_state | Tri-state output; follows input A when OE is high, high-impedance when OE is low |
| 5 | VCC | power_in | Power supply pin; operating voltage range 4.5V to 5.5V per recommended operating conditions |
