# TPG1066C5

**TECH PUBLIC** · Analog Switches, Multiplexers · SOT-353

TPG1066C5 from TECH PUBLIC, in a SOT-353. 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 | NO | passive | Normally open analog switch port, connected to COM when IN is high; signal range -0.3 V to +5.5 V. |
| 2 | COM | passive | Common analog switch port; signal range -0.3 V to +5.5 V, continuous current up to ±50 mA. |
| 3 | GND | power_in | Ground. |
| 4 | IN | input | Digital control pin that connects COM to NO when high (VIH min 1.6 V at VCC 3.3-5.5 V), off when low (VIL max 0.6 V), 1.8 V logic compatible. |
| 5 | VCC | power_in | Supply voltage, recommended operating range 1.6 V to 5.5 V, absolute maximum -0.3 V to +6.5 V. |
