74HC125T14-13 from Diodes Incorporated, in a TSSOP-14. 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 | 1OE | input | Active-low data enable input; driving it high places output 1Y in the high-impedance state. |
| 2 | 1A | input | Data input for buffer 1, with Schmitt-trigger action at all inputs. |
| 3 | 1Y | tri_state | 3-state data output of buffer 1, high impedance when 1OE is high. |
| 4 | 2OE | input | Active-low data enable input; driving it high places output 2Y in the high-impedance state. |
| 5 | 2A | input | Data input for buffer 2, with Schmitt-trigger action at all inputs. |
| 6 | 2Y | tri_state | 3-state data output of buffer 2, high impedance when 2OE is high. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | 3Y | tri_state | 3-state data output of buffer 3, high impedance when 3OE is high. |
| 9 | 3A | input | Data input for buffer 3, with Schmitt-trigger action at all inputs. |
| 10 | 3OE | input | Active-low data enable input; driving it high places output 3Y in the high-impedance state. |
| 11 | 4Y | tri_state | 3-state data output of buffer 4, high impedance when 4OE is high. |
| 12 | 4A | input | Data input for buffer 4, with Schmitt-trigger action at all inputs. |
| 13 | 4OE | input | Active-low data enable input; driving it high places output 4Y in the high-impedance state. |
| 14 | VCC | power_in | Supply voltage, operating range 2.0V to 6.0V. |
