SN74AHC125PWR from Texas Instruments, 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 | Output enable for gate 1; when low, passes input 1A to output 1Y; when high, output is high-impedance. |
| 2 | 1A | input | Gate 1 input data signal. |
| 3 | 1Y | tri_state | Gate 1 tri-state output; passes 1A when 1OE is low, high-impedance when 1OE is high. |
| 4 | 2OE | input | Output enable for gate 2; when low, passes input 2A to output 2Y; when high, output is high-impedance. |
| 5 | 2A | input | Gate 2 input data signal. |
| 6 | 2Y | tri_state | Gate 2 tri-state output; passes 2A when 2OE is low, high-impedance when 2OE is high. |
| 7 | GND | power_in | Ground connection, 0V reference. |
| 8 | 3Y | tri_state | Gate 3 tri-state output; passes 3A when 3OE is low, high-impedance when 3OE is high. |
| 9 | 3A | input | Gate 3 input data signal. |
| 10 | 3OE | input | Output enable for gate 3; when low, passes input 3A to output 3Y; when high, output is high-impedance. |
| 11 | 4Y | tri_state | Gate 4 tri-state output; passes 4A when 4OE is low, high-impedance when 4OE is high. |
| 12 | 4A | input | Gate 4 input data signal. |
| 13 | 4OE | input | Output enable for gate 4; when low, passes input 4A to output 4Y; when high, output is high-impedance. |
| 14 | VCC | power_in | Power supply voltage pin, operating range 2V to 5.5V. |
