SN74AXC1T45QDCKRQ1 from Texas Instruments, in a SC-70-6. 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 | A port supply voltage; operating range 0.65V to 3.6V. |
| 2 | GND | power_in | Ground reference. |
| 3 | A | bidirectional | Bidirectional data I/O A referenced to VCCA; 0.65V to 3.6V operating voltage range. |
| 4 | B | bidirectional | Bidirectional data I/O B referenced to VCCB; 0.65V to 3.6V operating voltage range. |
| 5 | DIR | input | Direction control input referenced to VCCA; high enables A-to-B transfer, low enables B-to-A transfer. |
| 6 | VCCB | power_in | B port supply voltage; operating range 0.65V to 3.6V. |
