SN74AHCT1G126DBVR from Texas Instruments, in a SOT-23-5. 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 controlling 3-state output; when high, Y follows A; when low, Y is high-impedance. |
| 2 | A | input | Data input A with TTL-voltage compatibility (VIH = 2V, VIL = 0.8V); input voltage range 0V to 5.5V. |
| 3 | GND | power_in | Ground connection. |
| 4 | Y | tri_state | 3-state output with ±8mA output drive at 5V; high-impedance when OE is low. |
| 5 | VCC | power_in | Supply voltage pin; operating range 4.5V to 5.5V. |
