| 2 | 2OE | input | Output enable input (active LOW); outputs are 3-state and go high-impedance when 1OE or 2OE is HIGH. |
| 3 | Q0 | tri_state | 3-state flip-flop output. |
| 4 | Q1 | tri_state | 3-state flip-flop output. |
| 5 | Q2 | tri_state | 3-state flip-flop output. |
| 6 | Q3 | tri_state | 3-state flip-flop output. |
| 7 | CP | input | Clock input, LOW-to-HIGH edge triggered. |
| 8 | GND | power_in | Ground (0 V). |
| 9 | 1E | input | Data enable input (active LOW). |
| 10 | 2E | input | Data enable input (active LOW). |
| 11 | D3 | input | Data input. |
| 12 | D2 | input | Data input. |
| 13 | D1 | input | Data input. |
| 14 | D0 | input | Data input. |
| 15 | MR | input | Asynchronous master reset (active HIGH); clears the register. |
