Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VL | power_in | Logic input voltage, with +1.2V ≤ VL ≤ (VCC + 0.3V). |
| 2 | I/O VL1 | bidirectional | Input/output 1, referenced to VL. |
| 3 | I/O VL2 | bidirectional | Input/output 2, referenced to VL. |
| 4 | I/O VL3 | bidirectional | Input/output 3, referenced to VL. |
| 5 | I/O VL4 | bidirectional | Input/output 4, referenced to VL. |
| 6 | N.C. | unconnected | No connection; not internally connected. |
| 7 | GND | power_in | Ground. |
| 8 | THREE-STATE | input | Three-state output mode enable; pulling it low places the device in three-state output mode, where I/O VCC_ and I/O VL_ are high impedance, and logic is referenced to VL. |
| 9 | N.C. | unconnected | No connection; not internally connected. |
| 10 | I/O VCC4 | bidirectional | Input/output 4, referenced to VCC. |
| 11 | I/O VCC3 | bidirectional | Input/output 3, referenced to VCC. |
| 12 | I/O VCC2 | bidirectional | Input/output 2, referenced to VCC. |
| 13 | I/O VCC1 | bidirectional | Input/output 1, referenced to VCC. |
| 14 | VCC | power_in | Input voltage, with +1.65V ≤ VCC ≤ +5.5V. |
