Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Active-low 3-STATE enable input for buffer 0 (output O0 is high impedance when A0 is HIGH); input accepts 0V to 5.5V. |
| 2 | B0 | input | Data input of buffer 0, passed non-inverted to O0 when A0 is LOW; 0V to 5.5V recommended. |
| 3 | O0 | tri_state | 3-STATE output of buffer 0 that follows B0 when A0 is LOW and is high impedance when A0 is HIGH. |
| 4 | A1 | input | Active-low 3-STATE enable input for buffer 1 (output O1 is high impedance when A1 is HIGH); input accepts 0V to 5.5V. |
| 5 | B1 | input | Data input of buffer 1, passed non-inverted to O1 when A1 is LOW; 0V to 5.5V recommended. |
| 6 | O1 | tri_state | 3-STATE output of buffer 1 that follows B1 when A1 is LOW and is high impedance when A1 is HIGH. |
| 7 | GND | power_in | Ground pin (0V reference). |
| 8 | O3 | tri_state | 3-STATE output of buffer 3 that follows B3 when A3 is LOW and is high impedance when A3 is HIGH. |
| 9 | B3 | input | Data input of buffer 3, passed non-inverted to O3 when A3 is LOW; 0V to 5.5V recommended. |
| 10 | A3 | input | Active-low 3-STATE enable input for buffer 3 (output O3 is high impedance when A3 is HIGH); input accepts 0V to 5.5V. |
| 11 | O2 | tri_state | 3-STATE output of buffer 2 that follows B2 when A2 is LOW and is high impedance when A2 is HIGH. |
| 12 | B2 | input | Data input of buffer 2, passed non-inverted to O2 when A2 is LOW; 0V to 5.5V recommended. |
| 13 | A2 | input | Active-low 3-STATE enable input for buffer 2 (output O2 is high impedance when A2 is HIGH); input accepts 0V to 5.5V. |
| 14 | VCC | power_in | Positive supply voltage, 2.0V to 5.5V recommended operating range (absolute maximum 7.0V). |
