Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G1 | input | Active-low output enable 1; when G1 or G2 is high the Y outputs are in the high-impedance state. |
| 2 | A1 | input | Data input 1, accepts 0 to 5.5 V regardless of supply voltage. |
| 3 | A2 | input | Data input 2, accepts 0 to 5.5 V regardless of supply voltage. |
| 4 | A3 | input | Data input 3, accepts 0 to 5.5 V regardless of supply voltage. |
| 5 | A4 | input | Data input 4, accepts 0 to 5.5 V regardless of supply voltage. |
| 6 | A5 | input | Data input 5, accepts 0 to 5.5 V regardless of supply voltage. |
| 7 | A6 | input | Data input 6, accepts 0 to 5.5 V regardless of supply voltage. |
| 8 | A7 | input | Data input 7, accepts 0 to 5.5 V regardless of supply voltage. |
| 9 | A8 | input | Data input 8, accepts 0 to 5.5 V regardless of supply voltage. |
| 10 | GND | power_in | Ground (0 V) reference. |
| 11 | Y8 | tri_state | Non-inverting 3-state output 8 following A8, high-impedance when G1 or G2 is high. |
| 12 | Y7 | tri_state | Non-inverting 3-state output 7 following A7, high-impedance when G1 or G2 is high. |
| 13 | Y6 | tri_state | Non-inverting 3-state output 6 following A6, high-impedance when G1 or G2 is high. |
| 14 | Y5 | tri_state | Non-inverting 3-state output 5 following A5, high-impedance when G1 or G2 is high. |
| 15 | Y4 | tri_state | Non-inverting 3-state output 4 following A4, high-impedance when G1 or G2 is high. |
| 16 | Y3 | tri_state | Non-inverting 3-state output 3 following A3, high-impedance when G1 or G2 is high. |
| 17 | Y2 | tri_state | Non-inverting 3-state output 2 following A2, high-impedance when G1 or G2 is high. |
| 18 | Y1 | tri_state | Non-inverting 3-state output 1 following A1, high-impedance when G1 or G2 is high. |
| 19 | G2 | input | Active-low output enable 2; when G1 or G2 is high the Y outputs are in the high-impedance state. |
| 20 | VCC | power_in | Supply voltage, operating range 2.0 to 5.5 V. |

Package_SO:SOP-20_7.5x12.8mm_P1.27mm - 3D model: SOP-20, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 2.65 mm nominal SOIC height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
