SN74LVC1T45DBVRE4 from Texas Instruments, in a SOT-23-6. 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 | System 1 power supply voltage operating from 1.65V to 5.5V |
| 2 | GND | power_in | Device ground |
| 3 | A | bidirectional | Port A bidirectional I/O with output level referenced to VCCA |
| 4 | B | bidirectional | Port B bidirectional I/O with input threshold referenced to VCCB |
| 5 | DIR | input | Direction control input; low level selects B-to-A transmission path, high level selects A-to-B transmission path |
| 6 | VCCB | power_in | System 2 power supply voltage operating from 1.65V to 5.5V |
