SN74AXCH1T45DCKR 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 supply voltage; 0.65 V ≤ VCCA ≤ 3.6 V. |
| 2 | GND | power_in | Ground reference. |
| 3 | A | bidirectional | Input/output A referenced to VCCA for bus transceiver signal propagation. |
| 4 | B | bidirectional | Input/output B referenced to VCCB for bus transceiver signal propagation. |
| 5 | DIR | input | Direction control signal; HIGH enables A to B translation, LOW enables B to A translation. |
| 6 | VCCB | power_in | B-port supply voltage; 0.65 V ≤ VCCB ≤ 3.6 V. |
