## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Data input A0 of gate 0; the datasheet states inputs are 5.0 V tolerant (VI up to 5.5 V) and must not be left floating. |
| 2 | B0 | input | Data input B0 of gate 0; the datasheet states inputs are 5.0 V tolerant (VI up to 5.5 V) and must not be left floating. |
| 3 | O0 | output | OR gate output O0 with 24 mA balanced sink and source capability at VCC 3.0 V to 3.6 V. |
| 4 | A1 | input | Data input A1 of gate 1; the datasheet states inputs are 5.0 V tolerant (VI up to 5.5 V) and must not be left floating. |
| 5 | B1 | input | Data input B1 of gate 1; the datasheet states inputs are 5.0 V tolerant (VI up to 5.5 V) and must not be left floating. |
| 6 | O1 | output | OR gate output O1 with 24 mA balanced sink and source capability at VCC 3.0 V to 3.6 V. |
| 7 | GND | power_in | Ground reference; the datasheet limits ground current to 100 mA per ground pin. |
| 8 | O3 | output | OR gate output O3 with 24 mA balanced sink and source capability at VCC 3.0 V to 3.6 V. |
| 9 | B3 | input | Data input B3 of gate 3; the datasheet states inputs are 5.0 V tolerant (VI up to 5.5 V) and must not be left floating. |
| 10 | A3 | input | Data input A3 of gate 3; the datasheet states inputs are 5.0 V tolerant (VI up to 5.5 V) and must not be left floating. |
| 11 | O2 | output | OR gate output O2 with 24 mA balanced sink and source capability at VCC 3.0 V to 3.6 V. |
| 12 | B2 | input | Data input B2 of gate 2; the datasheet states inputs are 5.0 V tolerant (VI up to 5.5 V) and must not be left floating. |
| 13 | A2 | input | Data input A2 of gate 2; the datasheet states inputs are 5.0 V tolerant (VI up to 5.5 V) and must not be left floating. |
| 14 | VCC | power_in | Supply pin; the datasheet specifies operation from 2.3 V to 3.6 V with 100 mA maximum supply current per supply pin. |
