74LVC126AS14-13 from Diodes Incorporated, in a SO-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 Active-high output enable for buffer 1; driving it low places output 1Y in the high-impedance state.
2 1A input Data input for buffer 1; inputs are tolerant to 5.5V and unused inputs should be held at VCC or ground.
3 1Y tri_state Three-state data output of buffer 1, high impedance when 1OE is low.
4 2OE input Active-high output enable for buffer 2; driving it low places output 2Y in the high-impedance state.
5 2A input Data input for buffer 2; inputs are tolerant to 5.5V and unused inputs should be held at VCC or ground.
6 2Y tri_state Three-state data output of buffer 2, high impedance when 2OE is low.
7 GND power_in Ground reference for the device.
8 3Y tri_state Three-state data output of buffer 3, high impedance when 3OE is low.
9 3A input Data input for buffer 3; inputs are tolerant to 5.5V and unused inputs should be held at VCC or ground.
10 3OE input Active-high output enable for buffer 3; driving it low places output 3Y in the high-impedance state.
11 4Y tri_state Three-state data output of buffer 4, high impedance when 4OE is low.
12 4A input Data input for buffer 4; inputs are tolerant to 5.5V and unused inputs should be held at VCC or ground.
13 4OE input Active-high output enable for buffer 4; driving it low places output 4Y in the high-impedance state.
14 VCC power_in Supply voltage, specified from 1.65V to 5.5V.
