STG719STR from STMicroelectronics, in a SOT-23-6. 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 | IN | input | Digital control input selecting which independent channel (S1 or S2) is connected to the common D pin. Low level connects S1 to D; High level connects S2 to D. CMOS logic thresholds referenced to VCC (VIH=2.0V at 3.3V, 2.4V at 5V). |
| 2 | VCC | power_in | Positive supply voltage. Operating range 1.8V to 5.5V (absolute max -0.5V to +7.0V). Quiescent current is 1µA max. |
| 3 | GND | power_in | Ground reference (0V). |
| 4 | S1 | passive | Independent analog switch channel 1. Bidirectional analog signal path connected to D when IN is Low. RON = 4Ω max at VCC=5V; signal range 0 to VCC. |
| 5 | D | passive | Common analog switch pole. Bidirectional pin that connects to either S1 or S2 depending on IN state. |
| 6 | S2 | passive | Independent analog switch channel 2. Bidirectional analog signal path connected to D when IN is High. RON = 4Ω max at VCC=5V; signal range 0 to VCC. |
