**Texas Instruments** · Buffers, Drivers, Receivers, Transceivers · SC-70-5

SN74AHC1G125DCKT 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 input; high level disables the tri-state output to high-impedance state. |
| 2 | A | input | Data Input to the buffer; logic level is transferred to output Y when OE is low. |
| 3 | GND | power_in | Ground reference pin. |
| 4 | Y | tri_state | Tri-state Output with ±8mA drive capability at 5V; high-impedance state when OE is high. |
| 5 | VCC | power_in | Power Supply pin; operating voltage range 2V to 5.5V. |
