STG3682QTR

STMicroelectronics · Analog Switches, Multiplexers · QFN-10(1.8x1.4)

STG3682QTR from STMicroelectronics, in a QFN-10(1.8x1.4). 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 1S1 bidirectional Independent switch terminal of pair 1; connects to common D1 when SEL1 is high via ON-resistance of 4.6Ω at VCC=4.3V.
2 D1 bidirectional Common terminal for switch pair 1; routes to 1S1 when SEL1 is high or to 1S2 when SEL1 is low.
3 1S2 bidirectional Independent switch terminal of pair 1; connects to common D1 when SEL1 is low via ON-resistance of 4.6Ω at VCC=4.3V.
4 SEL2 input Digital control input for switch pair 2; high selects 2S1 (S1 ON), low selects 2S2 (S2 ON).
5 GND power_in Ground (0V) reference.
6 2S1 bidirectional Independent switch terminal of pair 2; connects to common D2 when SEL2 is high via ON-resistance of 4.6Ω at VCC=4.3V.
7 D2 bidirectional Common terminal for switch pair 2; routes to 2S1 when SEL2 is high or to 2S2 when SEL2 is low.
8 2S2 bidirectional Independent switch terminal of pair 2; connects to common D2 when SEL2 is low via ON-resistance of 4.6Ω at VCC=4.3V.
9 VCC power_in Positive supply voltage; operating range 1.65V to 4.3V single supply.
10 SEL1 input Digital control input for switch pair 1; high selects 1S1 (S1 ON), low selects 1S2 (S2 ON).
