SN74CB3Q3306ADCUR from Texas Instruments, in a VSSOP-8. 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 | Output enable input for switch 1; when low the switch is ON, when high it is OFF. |
| 2 | 1A | bidirectional | Bidirectional data I/O port A of channel 1; supports 0-5V switching levels with 3.3V VCC. |
| 3 | 1B | bidirectional | Bidirectional data I/O port B of channel 1; supports 0-5V switching levels with 3.3V VCC. |
| 4 | GND | power_in | Ground reference potential for the device. |
| 5 | 2A | bidirectional | Bidirectional data I/O port A of channel 2; supports 0-5V switching levels with 3.3V VCC. |
| 6 | 2B | bidirectional | Bidirectional data I/O port B of channel 2; supports 0-5V switching levels with 3.3V VCC. |
| 7 | 2OE | input | Output enable input for switch 2; when low the switch is ON, when high it is OFF. |
| 8 | VCC | power_out | Positive power supply input with recommended operating range of 2.3V to 3.6V. |
