Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCCA | power_in | A-port supply voltage, which must be within 1.65 V to 5.5 V; the control pins DIR and OE are referenced to this supply. |
| 2 | DIR | input | Direction-control input that sets whether data is transferred from the B bus to the A bus or from the A bus to the B bus. |
| 3 | A1 | bidirectional | Input/output A1, referenced to VCCA. |
| 4 | A2 | bidirectional | Input/output A2, referenced to VCCA. |
| 5 | A3 | bidirectional | Input/output A3, referenced to VCCA. |
| 6 | A4 | bidirectional | Input/output A4, referenced to VCCA. |
| 7 | A5 | bidirectional | Input/output A5, referenced to VCCA. |
| 8 | A6 | bidirectional | Input/output A6, referenced to VCCA. |
| 9 | A7 | bidirectional | Input/output A7, referenced to VCCA. |
| 10 | A8 | bidirectional | Input/output A8, referenced to VCCA. |
| 11 | GND | power_in | Ground pin; the device has three GND pins (11, 12, 13). |
| 12 | GND | power_in | Ground pin; the device has three GND pins (11, 12, 13). |
| 13 | GND | power_in | Ground pin; the device has three GND pins (11, 12, 13). |
| 14 | B8 | bidirectional | Input/output B8, referenced to VCCB. |

| 21 | B1 | bidirectional | Input/output B1, referenced to VCCB. |
| 22 | OE | input | Active-low output enable (OE with overline); pulling it high places all outputs in 3-state mode, and it is referenced to VCCA. |
| 23 | VCCB | power_in | B-port supply voltage, which must be within 1.65 V to 5.5 V. |
| 24 | VCCB | power_in | B-port supply voltage, which must be within 1.65 V to 5.5 V. |
