SN74HCS125PWR 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 | Channel 1 Output Enable, active low; Schmitt-trigger input that drives output 1Y to high-impedance when high |
| 2 | 1A | input | Channel 1 input A; Schmitt-trigger input |
| 3 | 1Y | tri_state | Channel 1 output Y; tri-state output, high-impedance when 1OE is high, otherwise buffers 1A input |
| 4 | 2OE | input | Channel 2 Output Enable, active low; Schmitt-trigger input that drives output 2Y to high-impedance when high |
| 5 | 2A | input | Channel 2 input A; Schmitt-trigger input |
| 6 | 2Y | tri_state | Channel 2 output Y; tri-state output, high-impedance when 2OE is high, otherwise buffers 2A input |
| 7 | GND | power_in | Ground |
| 8 | 3Y | tri_state | Channel 3 output Y; tri-state output, high-impedance when 3OE is high, otherwise buffers 3A input |
| 9 | 3A | input | Channel 3 input A; Schmitt-trigger input |
| 10 | 3OE | input | Channel 3 Output Enable, active low; Schmitt-trigger input that drives output 3Y to high-impedance when high |
| 11 | 4Y | tri_state | Channel 4 output Y; tri-state output, high-impedance when 4OE is high, otherwise buffers 4A input |
| 12 | 4A | input | Channel 4 input A; Schmitt-trigger input |
| 13 | 4OE | input | Channel 4 Output Enable, active low; Schmitt-trigger input that drives output 4Y to high-impedance when high |
| 14 | VCC | power_in | Positive supply voltage, 2V to 6V |
