1P1G125QDCKRQ1 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 | Active-low output enable input; output Y enters high-impedance state when OE is high |
| 2 | A | input | Logic input A for buffer function; input voltage range 0V to 5.5V overvoltage tolerant |
| 3 | GND | power_in | Ground reference; return path for device supply and signal currents |
| 4 | Y | tri_state | Tri-state output implementing logic function Y = A when OE is low; drive capability ±24mA at VCC = 3.3V |
| 5 | VCC | power_in | Positive power supply; rated for 1.65V to 5.5V operation with maximum quiescent current 10µA |
