74AVCH1T45W6-7 from Diodes Incorporated, in a SOT-26. 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 from 1.2 V to 3.6 V. |
| 2 | GND | power_in | Ground reference for the device, which must be at 0 V for the 3-state and Ioff behavior to apply. |
| 3 | A | bidirectional | Data input/output for the A side, designed to track VCC(A), with the output in high impedance when either supply is at 0 V and inputs accepting up to 4.6 V. |
| 4 | B | bidirectional | Data input/output for the B side, designed to track VCC(B), with the output in high impedance when either supply is at 0 V and inputs accepting up to 4.6 V. |
| 5 | DIR | input | Direction control; a high level makes A the input and B the output, a low level reverses them, and its logic levels are referenced to VCC(A). |
| 6 | VCC(B) | power_in | Supply for I/O pin B, operating from 1.2 V to 3.6 V. |
