Pinout
The SGM3157 is a single-pole, double-throw (SPDT) analog switch. It typically comes in a 6-pin SOT-23 package. Here are the pin functions:
1. VCC: Power Supply Pin.
2. GND: Ground Pin.
3. NC (Normally Closed): Normally closed terminal of the switch.
4. NO (Normally Open): Normally open terminal of the switch.
5. COM (Common): Common terminal of the switch that connects to either NC or NO.
6. IN (Control Input): Digital control input that determines which terminal (NC or NO) is connected to the COM pin.
The SGM3157 operates with a control logic where a high or low signal on the IN pin will toggle the connection between the COM pin and either the NC or NO pin. It is used in applications for signal routing where low on-resistance and fast switching are advantageous.
