SN74LV126ADR 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 | Channel 1 output enable input; output 1Y is high-impedance when 1OE is low, otherwise passes data from 1A |
| 2 | 1A | input | Channel 1 input data; logic level passed to 1Y when 1OE is high |
| 3 | 1Y | tri_state | Channel 1 tri-state output; reflects 1A when 1OE is high, high-impedance when 1OE is low, maximum output current ±35mA |
| 4 | 2OE | input | Channel 2 output enable input; output 2Y is high-impedance when 2OE is low, otherwise passes data from 2A |
| 5 | 2A | input | Channel 2 input data; logic level passed to 2Y when 2OE is high |
| 6 | 2Y | tri_state | Channel 2 tri-state output; reflects 2A when 2OE is high, high-impedance when 2OE is low, maximum output current ±35mA |
| 7 | GND | power_in | Ground (0V reference); maximum continuous current ±70mA |
| 8 | 3Y | tri_state | Channel 3 tri-state output; reflects 3A when 3OE is high, high-impedance when 3OE is low, maximum output current ±35mA |
| 9 | 3A | input | Channel 3 input data; logic level passed to 3Y when 3OE is high |
| 10 | 3OE | input | Channel 3 output enable input; output 3Y is high-impedance when 3OE is low, otherwise passes data from 3A |
| 11 | 4Y | tri_state | Channel 4 tri-state output; reflects 4A when 4OE is high, high-impedance when 4OE is low, maximum output current ±35mA |
| 12 | 4A | input | Channel 4 input data; logic level passed to 4Y when 4OE is high |
| 13 | 4OE | input | Channel 4 output enable input; output 4Y is high-impedance when 4OE is low, otherwise passes data from 4A |
| 14 | VCC | power_in | Positive supply voltage; 2V to 5.5V rated, maximum continuous current ±70mA |
