74LVC2244APW from Nexperia, in a TSSOP-20. 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 Output enable input for outputs 1Y0 to 1Y3, active LOW; a HIGH level puts those outputs in the high-impedance OFF-state.
2 1A0 input Data input 1A0; recommended input voltage range is 0 V to 5.5 V, so 3.3 V and 5 V drivers can be used.
3 2Y0 output Data output 2Y0; 3-state output that is high-impedance (Z) when 2OE is HIGH.
4 1A1 input Data input 1A1; recommended input voltage range is 0 V to 5.5 V, so 3.3 V and 5 V drivers can be used.
5 2Y1 output Data output 2Y1; 3-state output that is high-impedance (Z) when 2OE is HIGH.
6 1A2 input Data input 1A2; recommended input voltage range is 0 V to 5.5 V, so 3.3 V and 5 V drivers can be used.
7 2Y2 output Data output 2Y2; 3-state output that is high-impedance (Z) when 2OE is HIGH.
8 1A3 input Data input 1A3; recommended input voltage range is 0 V to 5.5 V, so 3.3 V and 5 V drivers can be used.
9 2Y3 output Data output 2Y3; 3-state output that is high-impedance (Z) when 2OE is HIGH.
10 GND power_in Ground reference (0 V) for all voltages in the device.
11 2A3 input Data input 2A3; recommended input voltage range is 0 V to 5.5 V, so 3.3 V and 5 V drivers can be used.
12 1Y3 output Data output 1Y3; 3-state output that is high-impedance (Z) when 1OE is HIGH.
13 2A2 input Data input 2A2; recommended input voltage range is 0 V to 5.5 V, so 3.3 V and 5 V drivers can be used.
14 1Y2 output Data output 1Y2; 3-state output that is high-impedance (Z) when 1OE is HIGH.
15 2A1 input Data input 2A1; recommended input voltage range is 0 V to 5.5 V, so 3.3 V and 5 V drivers can be used.
16 1Y1 output Data output 1Y1; 3-state output that is high-impedance (Z) when 1OE is HIGH.
17 2A0 input Data input 2A0; recommended input voltage range is 0 V to 5.5 V, so 3.3 V and 5 V drivers can be used.
18 1Y0 output Data output 1Y0; 3-state output that is high-impedance (Z) when 1OE is HIGH.
19 2OE input Output enable input for outputs 2Y0 to 2Y3, active LOW; a HIGH level puts those outputs in the high-impedance OFF-state.
20 VCC power_in Supply voltage; recommended range 1.65 V to 3.6 V (functional down to 1.2 V), absolute maximum 6.5 V.
