| 3 | 1Y | tri_state | Three-state data output of buffer 1, high impedance when 1OE is low. |
| 4 | 2OE | input | Data enable input (active high); driving it low places output 2Y in the high impedance state. |
| 5 | 2A | input | Data input for buffer 2, tolerant to 5.5V. |
| 6 | 2Y | tri_state | Three-state data output of buffer 2, high impedance when 2OE is low. |
| 7 | GND | power_in | Ground reference pin. |
| 8 | 3Y | tri_state | Three-state data output of buffer 3, high impedance when 3OE is low. |
| 9 | 3A | input | Data input for buffer 3, tolerant to 5.5V. |
| 10 | 3OE | input | Data enable input (active high); driving it low places output 3Y in the high impedance state. |
| 11 | 4Y | tri_state | Three-state data output of buffer 4, high impedance when 4OE is low. |
| 12 | 4A | input | Data input for buffer 4, tolerant to 5.5V. |
