MM74HC125MTC from onsemi, 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 C1 input 3-STATE control input for buffer 1; taken high puts Y1 into high impedance (active-low enable).
2 A1 input Data input of buffer 1, with low input current of 1µA maximum.
3 Y1 tri_state 3-STATE non-inverting output of buffer 1 that follows A1 when C1 is low and is high impedance when C1 is high.
4 C2 input 3-STATE control input for buffer 2; taken high puts Y2 into high impedance (active-low enable).
5 A2 input Data input of buffer 2, with low input current of 1µA maximum.
6 Y2 tri_state 3-STATE non-inverting output of buffer 2 that follows A2 when C2 is low and is high impedance when C2 is high.
7 GND power_in Ground pin, 0V reference for all voltages.
8 Y3 tri_state 3-STATE non-inverting output of buffer 3 that follows A3 when C3 is low and is high impedance when C3 is high.
9 A3 input Data input of buffer 3, with low input current of 1µA maximum.
10 C3 input 3-STATE control input for buffer 3; taken high puts Y3 into high impedance (active-low enable).
11 Y4 tri_state 3-STATE non-inverting output of buffer 4 that follows A4 when C4 is low and is high impedance when C4 is high.
12 A4 input Data input of buffer 4, with low input current of 1µA maximum.
13 C4 input 3-STATE control input for buffer 4; taken high puts Y4 into high impedance (active-low enable).
14 VCC power_in Positive supply pin, recommended operating range 2V to 6V (absolute maximum -0.5 to +7.0V).
