74LVC126AT14-13 from Diodes Incorporated, 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 Data enable input (active high); driving it low places output 1Y in the high impedance state.
2 1A input Data input for buffer 1, tolerant to 5.5V.
3 1Y tri_state Three-state data output of buffer 1, high impedance when 1OE is low.
4 2OE input Data enable input (active high); driving it low places output 2Y in the high impedance state.
5 2A input Data input for buffer 2, tolerant to 5.5V.
6 2Y tri_state Three-state data output of buffer 2, high impedance when 2OE is low.
7 GND power_in Ground reference pin.
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, tolerant to 5.5V.
10 3OE input Data enable input (active high); 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, tolerant to 5.5V.
13 4OE input Data enable input (active high); driving it low places output 4Y in the high impedance state.
14 VCC power_in Supply voltage pin, specified for operation from 1.65V to 5.50V.
