Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VCCA | power_in | A-port supply voltage. 1.2 V ≤ VCCA ≤ 3.6 V and VCCA ≤ VCCB. Sets the logic level and reference for the A-side I/Os and the OE input circuit. |+| 2 | A1 | bidirectional | Input/output 1, referenced to VCCA. Automatic direction sensing between A1 and B1 for bidirectional level translation. |+| 3 | A2 | bidirectional | Input/output 2, referenced to VCCA. Paired with B2 for bidirectional level translation. |+| 4 | A3 | bidirectional | Input/output 3, referenced to VCCA. Paired with B3 for bidirectional level translation. |+| 5 | A4 | bidirectional | Input/output 4, referenced to VCCA. Paired with B4 for bidirectional level translation. |+| 6 | NC | unconnected | No connection. Not internally connected. |+| 7 | GND | power_in | Ground reference for the device. |+| 8 | OE | input | Tri-state output-mode enable, referenced to VCCA. Pull OE low to place all outputs in the high-impedance state; must be tied to GND through a pulldown resistor during power sequencing to ensure high-Z at power up/down. |+| 9 | NC | unconnected | No connection. Not internally connected. |+| 10 | B4 | bidirectional | Input/output 4, referenced to VCCB. Paired with A4 for bidirectional level translation. |+| 11 | B3 | bidirectional | Input/output 3, referenced to VCCB. Paired with A3 for bidirectional level translation. |+| 12 | B2 | bidirectional | Input/output 2, referenced to VCCB. Paired with A2 for bidirectional level translation. |+| 13 | B1 | bidirectional | Input/output 1, referenced to VCCB. Paired with A1 for bidirectional level translation. |+| 14 | VCCB | power_in | B-port supply voltage. 1.65 V ≤ VCCB ≤ 5.5 V and must be ≥ VCCA.
