Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SOIC-14
SN74F125DR 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 1OE is high and enabled when it is low. |
| 2 | 1A | input | Data input of buffer 1; unused inputs must be held at VCC or GND to ensure proper device operation. |
| 3 | 1Y | tri_state | 3-state output of buffer 1, which goes to high impedance when 1OE is high. |
| 4 | 2OE | input | Output enable for buffer 2; the 2Y output is disabled (high impedance) when 2OE is high and enabled when it is low. |
| 5 | 2A | input | Data input of buffer 2; unused inputs must be held at VCC or GND to ensure proper device operation. |
| 6 | 2Y | tri_state | 3-state output of buffer 2, which goes to high impedance when 2OE is high. |
| 7 | GND | power_in | Device ground reference pin. |
| 8 | 3Y | tri_state | 3-state output of buffer 3, which goes to high impedance when 3OE is high. |
| 9 | 3A | input | Data input of buffer 3; 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 3OE is high and enabled when it is low. |
| 11 | 4Y | tri_state | 3-state output of buffer 4, which goes to high impedance when 4OE is high. |
| 12 | 4A | input | Data input of buffer 4; 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 4OE is high and enabled when it is low. |
| 14 | VCC | power_in | Supply voltage pin; recommended range is 4.5 V to 5.5 V with 5 V nominal. |
