SN74ABT125PWR 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 input for buffer 1; low level enables output 1Y, high level forces 1Y to high-impedance state. |
| 2 | 1A | input | Data input for buffer 1; drives output 1Y when output is enabled. |
| 3 | 1Y | tri_state | Tristate output of buffer 1; buffered 1A when 1OE is low, high-impedance when 1OE is high. |
| 4 | 2OE | input | Output-enable input for buffer 2; low level enables output 2Y, high level forces 2Y to high-impedance state. |
| 5 | 2A | input | Data input for buffer 2; drives output 2Y when output is enabled. |
| 6 | 2Y | tri_state | Tristate output of buffer 2; buffered 2A when 2OE is low, high-impedance when 2OE is high. |
| 7 | GND | power_in | Ground; negative supply voltage reference. |
| 8 | 3Y | tri_state | Tristate output of buffer 3; buffered 3A when 3OE is low, high-impedance when 3OE is high. |
| 9 | 3A | input | Data input for buffer 3; drives output 3Y when output is enabled. |
| 10 | 3OE | input | Output-enable input for buffer 3; low level enables output 3Y, high level forces 3Y to high-impedance state. |
| 11 | 4Y | tri_state | Tristate output of buffer 4; buffered 4A when 4OE is low, high-impedance when 4OE is high. |
| 12 | 4A | input | Data input for buffer 4; drives output 4Y when output is enabled. |
| 13 | 4OE | input | Output-enable input for buffer 4; low level enables output 4Y, high level forces 4Y to high-impedance state. |
| 14 | VCC | power_in | Positive supply voltage; rated 4.5 V to 5.5 V per recommended operating conditions. |
