Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | input | Data input A of 2-input AND gate 1; inputs are specified to stay between 0 V and VCC, with input current at most 1 uA at VCC = 6.0 V. |
| 2 | B1 | input | Data input B of 2-input AND gate 1; inputs are specified to stay between 0 V and VCC, with input current at most 1 uA at VCC = 6.0 V. |
| 3 | Y1 | output | Push-pull buffered output of AND gate 1; absolute maximum output current per pin is 25 mA. |
| 4 | A2 | input | Data input A of 2-input AND gate 2; inputs are specified to stay between 0 V and VCC, with input current at most 1 uA at VCC = 6.0 V. |
| 5 | B2 | input | Data input B of 2-input AND gate 2; inputs are specified to stay between 0 V and VCC, with input current at most 1 uA at VCC = 6.0 V. |
| 6 | Y2 | output | Push-pull buffered output of AND gate 2; absolute maximum output current per pin is 25 mA. |
| 7 | GND | power_in | Ground reference pin; the absolute maximum VCC or GND current is 50 mA. |
| 8 | Y3 | output | Push-pull buffered output of AND gate 3; absolute maximum output current per pin is 25 mA. |
| 9 | A3 | input | Data input A of 2-input AND gate 3; inputs are specified to stay between 0 V and VCC, with input current at most 1 uA at VCC = 6.0 V. |
| 10 | B3 | input | Data input B of 2-input AND gate 3; inputs are specified to stay between 0 V and VCC, with input current at most 1 uA at VCC = 6.0 V. |
| 11 | Y4 | output | Push-pull buffered output of AND gate 4; absolute maximum output current per pin is 25 mA. |
| 12 | A4 | input | Data input A of 2-input AND gate 4; inputs are specified to stay between 0 V and VCC, with input current at most 1 uA at VCC = 6.0 V. |
| 13 | B4 | input | Data input B of 2-input AND gate 4; inputs are specified to stay between 0 V and VCC, with input current at most 1 uA at VCC = 6.0 V. |
| 14 | VCC | power_in | Supply pin; operating range is 2.0 V to 6.0 V, with an absolute maximum of 6.5 V. |
