SN64BCT125AD 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 | Active-high output enable for buffer 1; when 1OE is high the 1Y output is disabled to the high-impedance state. |
| 2 | 1A | input | Data input to buffer 1, whose logic level is passed to output 1Y when 1OE is low. |
| 3 | 1Y | tri_state | 3-state output of buffer 1 that drives bus lines and goes high impedance when 1OE is high. |
| 4 | 2OE | input | Active-high output enable for buffer 2; when 2OE is high the 2Y output is disabled to the high-impedance state. |
| 5 | 2A | input | Data input to buffer 2, whose logic level is passed to output 2Y when 2OE is low. |
| 6 | 2Y | tri_state | 3-state output of buffer 2 that drives bus lines and goes high impedance when 2OE is high. |
| 7 | GND | power_in | Ground reference pin for the device. |
| 8 | 3Y | tri_state | 3-state output of buffer 3 that drives bus lines and goes high impedance when 3OE is high. |
| 9 | 3A | input | Data input to buffer 3, whose logic level is passed to output 3Y when 3OE is low. |
| 10 | 3OE | input | Active-high output enable for buffer 3; when 3OE is high the 3Y output is disabled to the high-impedance state. |
| 11 | 4Y | tri_state | 3-state output of buffer 4 that drives bus lines and goes high impedance when 4OE is high. |
| 12 | 4A | input | Data input to buffer 4, whose logic level is passed to output 4Y when 4OE is low. |
| 13 | 4OE | input | Active-high output enable for buffer 4; when 4OE is high the 4Y output is disabled to the high-impedance state. |
| 14 | VCC | power_in | Supply voltage pin; recommended operating range is 4.5 V to 5.5 V (5 V nominal). |
