74AVC1T45DW-7 from Diodes Incorporated, in a SOT-363. 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 | VCC(A) | power_in | Supply for I/O pin A and reference for DIR, operating range 1.2V to 3.6V. |
| 2 | GND | power_in | Ground. |
| 3 | A | bidirectional | Data input/output tracking VCC(A); acts as input when DIR is high and output when DIR is low. |
| 4 | B | bidirectional | Data input/output tracking VCC(B); acts as output when DIR is high and input when DIR is low. |
| 5 | DIR | input | Direction control referenced to VCC(A): high makes A the input and B the output, low reverses it. |
| 6 | VCC(B) | power_in | Supply for I/O pin B, operating range 1.2V to 3.6V. |
