CAHCT1G125QDCKRQ1 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; when high, output Y is placed in high-impedance state; when low, output Y follows input A logic level. |
| 2 | A | input | Input A; data input to the single-channel buffer gate. |
| 3 | GND | power_in | Ground pin; connection to ground (negative supply). |
| 4 | Y | tri_state | Output Y; tri-state output that follows input A when OE is low, or enters high-impedance state when OE is high. |
| 5 | VCC | power_in | Power supply pin; connection to positive supply voltage in the range 3 V to 5.5 V. |
