74VHC125MTCX 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 A0 input Active-low 3-STATE enable input for buffer 0 (output O0 is high impedance when A0 is HIGH); input accepts 0V to 5.5V.
2 B0 input Data input of buffer 0, passed non-inverted to O0 when A0 is LOW; 0V to 5.5V recommended.
3 O0 tri_state 3-STATE output of buffer 0 that follows B0 when A0 is LOW and is high impedance when A0 is HIGH.
4 A1 input Active-low 3-STATE enable input for buffer 1 (output O1 is high impedance when A1 is HIGH); input accepts 0V to 5.5V.
5 B1 input Data input of buffer 1, passed non-inverted to O1 when A1 is LOW; 0V to 5.5V recommended.
6 O1 tri_state 3-STATE output of buffer 1 that follows B1 when A1 is LOW and is high impedance when A1 is HIGH.
7 GND power_in Ground pin (0V reference).
8 O3 tri_state 3-STATE output of buffer 3 that follows B3 when A3 is LOW and is high impedance when A3 is HIGH.
9 B3 input Data input of buffer 3, passed non-inverted to O3 when A3 is LOW; 0V to 5.5V recommended.
10 A3 input Active-low 3-STATE enable input for buffer 3 (output O3 is high impedance when A3 is HIGH); input accepts 0V to 5.5V.
11 O2 tri_state 3-STATE output of buffer 2 that follows B2 when A2 is LOW and is high impedance when A2 is HIGH.
12 B2 input Data input of buffer 2, passed non-inverted to O2 when A2 is LOW; 0V to 5.5V recommended.
13 A2 input Active-low 3-STATE enable input for buffer 2 (output O2 is high impedance when A2 is HIGH); input accepts 0V to 5.5V.
14 VCC power_in Positive supply voltage, 2.0V to 5.5V recommended operating range (absolute maximum 7.0V).
