SN74LV126APWR 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 channel 1; when low, output 1Y is disabled to high impedance, and when high the buffer passes 1A to 1Y. |
| 2 | 1A | input | Data input for channel 1; inputs are 5.5V tolerant at any valid VCC, allowing translation down to VCC. |
| 3 | 1Y | output | 3-state buffer output for channel 1, high impedance when 1OE is low. |
| 4 | 2OE | input | Output enable for channel 2; when low, output 2Y is disabled to high impedance, and when high the buffer passes 2A to 2Y. |
| 5 | 2A | input | Data input for channel 2; inputs are 5.5V tolerant at any valid VCC, allowing translation down to VCC. |
| 6 | 2Y | output | 3-state buffer output for channel 2, high impedance when 2OE is low. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | 3Y | output | 3-state buffer output for channel 3, high impedance when 3OE is low. |
| 9 | 3A | input | Data input for channel 3; inputs are 5.5V tolerant at any valid VCC, allowing translation down to VCC. |
| 10 | 3OE | input | Output enable for channel 3; when low, output 3Y is disabled to high impedance, and when high the buffer passes 3A to 3Y. |
| 11 | 4Y | output | 3-state buffer output for channel 4, high impedance when 4OE is low. |
| 12 | 4A | input | Data input for channel 4; inputs are 5.5V tolerant at any valid VCC, allowing translation down to VCC. |
| 13 | 4OE | input | Output enable for channel 4; when low, output 4Y is disabled to high impedance, and when high the buffer passes 4A to 4Y. |
| 14 | VCC | power_in | Positive supply; operating range is 2V to 5.5V per the recommended operating conditions. |
