74HC1G66GW from Nexperia, in a SOT-353. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Y | bidirectional | Analog switch terminal; carries switch current when enable is HIGH with ON resistance 18 Ω to 142 Ω and maximum current ±25 mA. |
| 2 | Z | bidirectional | Analog switch terminal; forms bidirectional connection with Y when enable is HIGH with ON resistance 18 Ω to 142 Ω and maximum current ±25 mA. |
| 3 | GND | power_in | Ground connection at 0 V reference. |
| 4 | E | input | Enable input (active HIGH); turns analog switch ON when HIGH, OFF when LOW; accepts input voltage 0 to VCC with threshold voltage ranging 0.5 V to 6.3 V depending on VCC. |
| 5 | VCC | power_in | Positive supply voltage; operating range 2.0 V to 10.0 V; determines switch ON resistance. |
