SN74CB3T3306DCUR from Texas Instruments, in a VSSOP-8-0.5mm. 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 | 1OE | input | Active-low enable for switch 1 that controls connection between 1A and 1B terminals when low. |
| 2 | 1A | bidirectional | Switch 1 A terminal providing bidirectional data I/O with 0-5V signaling level support. |
| 3 | 1B | bidirectional | Switch 1 B terminal providing bidirectional data I/O with 0-5V signaling level support. |
| 4 | GND | power_in | Ground reference pin at 0V. |
| 5 | 2A | bidirectional | Switch 2 A terminal providing bidirectional data I/O with 0-5V signaling level support. |
| 6 | 2B | bidirectional | Switch 2 B terminal providing bidirectional data I/O with 0-5V signaling level support. |
| 7 | 2OE | input | Active-low enable for switch 2 that controls connection between 2A and 2B terminals when low. |
| 8 | VCC | power_out | Supply voltage pin with recommended operating range 2.3V to 3.6V. |
