SN74LVC1T45DCKT from Texas Instruments, in a SC-70-6(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 | VCCA | power_in | SYSTEM-1 power supply voltage, accepts 1.65V to 5.5V. |
| 2 | GND | power_in | Device ground. |
| 3 | A | bidirectional | Bidirectional data I/O port referenced to VCCA, operates with 1.65V to 5.5V signals, output level dependent on VCCA voltage. |
| 4 | B | bidirectional | Bidirectional data I/O port referenced to VCCB, operates with 1.65V to 5.5V signals, input threshold dependent on VCCB voltage. |
| 5 | DIR | input | Direction control input referenced to VCCA; low logic level routes data from B to A, high logic level routes data from A to B. |
| 6 | VCCB | power_in | SYSTEM-2 power supply voltage, accepts 1.65V to 5.5V. |
