SN74AHC1G126DRLR from Texas Instruments, in a SOT-553-5. 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 high enables true data pass-through from A to Y, when low places output Y in high-impedance state. |
| 2 | A | input | Input A; accepts input voltages to 5.5V for down-voltage translation applications. |
| 3 | GND | power_in | Ground pin; provides 0V reference for internal circuits and external signal connections. |
| 4 | Y | tri_state | Output Y; 3-state output with ±8mA drive capability at 5V and maximum ±25mA continuous output current. |
| 5 | VCC | power_in | Power supply pin; accepts operating voltage from 2V to 5.5V for device operation. |
