| 3 | 1Y | tri_state | 3-state data output of buffer 1 that sinks or sources 8 mA at VCC = 4.5 V; continuous output current is limited to ±25 mA. |
| 4 | 2OE | input | Active-low data enable for buffer 2; a high level places output 2Y in the high-impedance state. |
| 5 | 2A | input | Data input of buffer 2 with Schmitt trigger action; inputs are tolerant to 5.5 V. |
| 6 | 2Y | tri_state | 3-state data output of buffer 2 that sinks or sources 8 mA at VCC = 4.5 V; continuous output current is limited to ±25 mA. |
| 7 | GND | power_in | Ground reference; continuous current through GND is limited to -75 mA. |
| 8 | 3Y | tri_state | 3-state data output of buffer 3 that sinks or sources 8 mA at VCC = 4.5 V; continuous output current is limited to ±25 mA. |
| 9 | 3A | input | Data input of buffer 3 with Schmitt trigger action; inputs are tolerant to 5.5 V. |
| 10 | 3OE | input | Active-low data enable for buffer 3; a high level places output 3Y in the high-impedance state. |
| 11 | 4Y | tri_state | 3-state data output of buffer 4 that sinks or sources 8 mA at VCC = 4.5 V; continuous output current is limited to ±25 mA. |
| 12 | 4A | input | Data input of buffer 4 with Schmitt trigger action; inputs are tolerant to 5.5 V. |
| 13 | 4OE | input | Active-low data enable for buffer 4; a high level places output 4Y in the high-impedance state. |
| 14 | VCC | power_in | Supply voltage with recommended range 2.0 V to 5.5 V and absolute maximum range -0.5 V to +7.0 V. |
