| 7 | GND | power_in | Ground reference (0 V) for the device. |
| 8 | 3Y | tri_state | Data output of buffer 3; 3-state output that is high-impedance when 3OE is HIGH, rated +64 mA and -32 mA. |
| 9 | 3A | input | Data input of buffer 3; bus-hold input with overvoltage tolerance to 5.5 V. |
| 10 | 3OE | input | Output enable input for buffer 3 (active LOW); a HIGH level forces output 3Y into the high-impedance OFF-state. |
| 11 | 4Y | tri_state | Data output of buffer 4; 3-state output that is high-impedance when 4OE is HIGH, rated +64 mA and -32 mA. |
| 12 | 4A | input | Data input of buffer 4; bus-hold input with overvoltage tolerance to 5.5 V. |
| 13 | 4OE | input | Output enable input for buffer 4 (active LOW); a HIGH level forces output 4Y into the high-impedance OFF-state. |
