SN74AVC2T45DCUR from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCCA | power_in | Supply voltage for the A port; A-side I/O output levels track VCCA, which the recommended operating conditions specify as 1.2 V to 3.6 V. |
| 2 | A1 | bidirectional | Input or output depending on the DIR state; the output level is referenced to VCCA. |
| 3 | A2 | bidirectional | Input or output depending on the DIR state; the output level is referenced to VCCA. |
| 4 | GND | power_in | Device ground; if either VCC input is tied to GND, both ports are placed in the high-impedance state. |
| 5 | DIR | input | Direction control input connected to GND or VCCA; DIR low transfers data from the B bus to the A bus and DIR high transfers data from the A bus to the B bus. |
| 6 | B2 | bidirectional | Input or output depending on the DIR state; the output level is referenced to VCCB. |
| 7 | B1 | bidirectional | Input or output depending on the DIR state; the output level is referenced to VCCB. |
| 8 | VCCB | power_in | Supply voltage for the B port; B-side I/O output levels track VCCB, which the recommended operating conditions specify as 1.2 V to 3.6 V. |
