SN74ALVC125DR from Texas Instruments, in a SOIC-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 | Output-enable for buffer 1; the 1Y output is disabled (high impedance) when this input is high, and OE should be tied to VCC through a pullup resistor to keep the output high-impedance during power up or power down. |
| 2 | 1A | input | Data input of buffer 1; all unused inputs must be held at VCC or GND to ensure proper device operation. |
| 3 | 1Y | tri_state | 3-state output of buffer 1, rated for ±24 mA output drive at 3.3 V. |
| 4 | 2OE | input | Output-enable for buffer 2; the 2Y output is disabled (high impedance) when this input is high. |
| 5 | 2A | input | Data input of buffer 2; all unused inputs must be held at VCC or GND to ensure proper device operation. |
| 6 | 2Y | tri_state | 3-state output of buffer 2, rated for ±24 mA output drive at 3.3 V. |
| 7 | GND | power_in | Ground reference pin for the device. |
| 8 | 3Y | tri_state | 3-state output of buffer 3, rated for ±24 mA output drive at 3.3 V. |
| 9 | 3A | input | Data input of buffer 3; all unused inputs must be held at VCC or GND to ensure proper device operation. |
| 10 | 3OE | input | Output-enable for buffer 3; the 3Y output is disabled (high impedance) when this input is high. |
| 11 | 4Y | tri_state | 3-state output of buffer 4, rated for ±24 mA output drive at 3.3 V. |
| 12 | 4A | input | Data input of buffer 4; all unused inputs must be held at VCC or GND to ensure proper device operation. |
| 13 | 4OE | input | Output-enable for buffer 4; the 4Y output is disabled (high impedance) when this input is high. |
| 14 | VCC | power_in | Supply voltage, specified from 1.65 V to 3.6 V. |
