## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1Y | output | Data output of gate 1; the datasheet function table gives HIGH on this pin unless all four inputs 1A to 1D are HIGH. |
| 2 | 1A | input | Data input A of gate 1; unused inputs must be connected to VDD, GND, or another input. |
| 3 | 1B | input | Data input B of gate 1; unused inputs must be connected to VDD, GND, or another input. |
| 4 | 1C | input | Data input C of gate 1; unused inputs must be connected to VDD, GND, or another input. |
| 5 | 1D | input | Data input D of gate 1; unused inputs must be connected to VDD, GND, or another input. |
| 6 | NC | unconnected | No connection; leave this pin unconnected. |
| 7 | GND | power_in | Ground (0V) reference for all voltages; the recommended VDD range of 3V to 15V is referenced to this pin. |
| 8 | NC | unconnected | No connection; leave this pin unconnected. |
| 9 | 2A | input | Data input A of gate 2; unused inputs must be connected to VDD, GND, or another input. |
| 10 | 2B | input | Data input B of gate 2; unused inputs must be connected to VDD, GND, or another input. |
| 11 | 2C | input | Data input C of gate 2; unused inputs must be connected to VDD, GND, or another input. |
| 12 | 2D | input | Data input D of gate 2; unused inputs must be connected to VDD, GND, or another input. |
| 13 | 2Y | output | Data output of gate 2; the datasheet function table gives HIGH on this pin unless all four inputs 2A to 2D are HIGH. |
| 14 | VDD | power_in | Supply voltage, recommended range 3V to 15V (absolute maximum +18V) referenced to GND. |
