SN74LVC1T45DC from lingxingic, in a SOT-363. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC(A) | power_in | Supply voltage A for port A and DIR input, operating range 1.2V to 5.5V |
| 2 | GND | power_in | Ground (0V) reference |
| 3 | A | bidirectional | Bidirectional single-bit data I/O port referenced to VCC(A) with 3-state output and ±50mA drive capability |
| 4 | B | bidirectional | Bidirectional single-bit data I/O port referenced to VCC(B) with 3-state output and ±50mA drive capability |
| 5 | DIR | input | Direction control input referenced to VCC(A); HIGH selects A to B transmission, LOW selects B to A transmission |
| 6 | VCC(B) | power_in | Supply voltage B for port B, operating range 1.2V to 5.5V |
