SN74AUC2G66DCTR from Texas Instruments, in a MSOP-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 | 1A | passive | Analog switch 1 A-side input/output terminal; the I/O port voltage is limited to 0 V to VCC (absolute maximum -0.5 V to VCC + 0.5 V). |
| 2 | 1B | passive | Analog switch 1 B-side input/output terminal; the I/O port voltage is limited to 0 V to VCC (absolute maximum -0.5 V to VCC + 0.5 V). |
| 3 | 2C | input | Control input for analog switch 2; logic low sets the switch OFF and logic high sets it ON, with control input voltage rated 0 V to 3.6 V. |
| 4 | GND | power_in | Ground reference; all voltages are specified with respect to ground. |
| 5 | 2A | passive | Analog switch 2 A-side input/output terminal; the I/O port voltage is limited to 0 V to VCC (absolute maximum -0.5 V to VCC + 0.5 V). |
| 6 | 2B | passive | Analog switch 2 B-side input/output terminal; the I/O port voltage is limited to 0 V to VCC (absolute maximum -0.5 V to VCC + 0.5 V). |
| 7 | 1C | input | Control input for analog switch 1; logic low sets the switch OFF and logic high sets it ON, with control input voltage rated 0 V to 3.6 V. |
| 8 | VCC | power_in | Supply voltage, recommended 0.8 V to 2.7 V (absolute maximum -0.5 V to 3.6 V); unused inputs must be held at VCC or GND. |
