SN74AVCH1T45DCKT from Texas Instruments, in a SC-70-6. 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 | A port power supply voltage, 1.2V ≤ VCCA ≤ 3.6V |
| 2 | GND | power_in | Ground connection |
| 3 | A | bidirectional | Input/output A referenced to VCCA, supports 1.2V to 3.6V I/O voltage with bus-hold circuitry |
| 4 | B | bidirectional | Input/output B referenced to VCCB, supports 1.2V to 3.6V I/O voltage with bus-hold circuitry |
| 5 | DIR | input | Direction control input referenced to VCCA; high level enables A to B data transmission, low level enables B to A data transmission |
| 6 | VCCB | power_in | B port power supply voltage, 1.2V ≤ VCCB ≤ 3.6V |
