SN74AXC2T45DCUR from Texas Instruments, in a VSSOP-8-0.5mm. 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 | Port A power supply voltage with range 0.65V ≤ VCCA ≤ 3.6V |
| 2 | A1 | bidirectional | Bidirectional I/O for Port A referenced to VCCA |
| 3 | A2 | bidirectional | Bidirectional I/O for Port A referenced to VCCA |
| 4 | GND | power_in | Ground |
| 5 | DIR | input | Direction control input referenced to VCCA; low enables B-to-A data transfer, high enables A-to-B data transfer |
| 6 | B2 | bidirectional | Bidirectional I/O for Port B referenced to VCCB |
| 7 | B1 | bidirectional | Bidirectional I/O for Port B referenced to VCCB |
| 8 | VCCB | power_in | Port B power supply voltage with range 0.65V ≤ VCCB ≤ 3.6V |
