Pinout

Pin Name Type Function
1 NO1 passive Channel 1 normally-open analog switch terminal. Bidirectional signal path connected to COM1 when IN1 is high. Handles rail-to-rail analog signals within 0 V to VCC, up to 100 mA continuous current.
2 COM1 passive Channel 1 common analog switch terminal. Bidirectional signal path connected to NO1 when IN1 is high. Handles rail-to-rail analog signals within 0 V to VCC.
3 NO2 passive Channel 2 normally-open analog switch terminal. Bidirectional signal path connected to COM2 when IN2 is high. Handles rail-to-rail analog signals within 0 V to VCC.
4 COM2 passive Channel 2 common analog switch terminal. Bidirectional signal path connected to NO2 when IN2 is high. Handles rail-to-rail analog signals within 0 V to VCC.
5 IN2 input Logic control input for channel 2. Drives high (VIH ≥ 1.4 V @ 3-V supply, ≥ 1.0 V @ 1.8-V supply) to close the switch between NO2 and COM2; low (VIL ≤ 0.5 V / 0.4 V) opens it. Input leakage ≤ ±10 nA. Can be driven up to 3.6 V regardless of VCC.
6 IN3 input Logic control input for channel 3. Drives high to close the switch between NO3 and COM3; low opens it. 1.8-V CMOS compatible with 3-V VCC. Input leakage ≤ ±10 nA over temperature.
7 GND power_in Ground reference. Continuous current through GND is rated ±100 mA maximum. All voltages are referenced to this pin.
8 NO3 passive Channel 3 normally-open analog switch terminal. Bidirectional signal path connected to COM3 when IN3 is high. Handles rail-to-rail analog signals within 0 V to VCC.
9 COM3 passive Channel 3 common analog switch terminal. Bidirectional signal path connected to NO3 when IN3 is high. Handles rail-to-rail analog signals within 0 V to VCC.
10 COM4 passive Channel 4 common analog switch terminal. Bidirectional signal path connected to NO4 when IN4 is high. Handles rail-to-rail analog signals within 0 V to VCC.
11 NO4 passive Channel 4 normally-open analog switch terminal. Bidirectional signal path connected to COM4 when IN4 is high. Handles rail-to-rail analog signals within 0 V to VCC.
12 IN4 input Logic control input for channel 4. Drives high to close the switch between NO4 and COM4; low opens it. 1.8-V CMOS compatible with 3-V VCC. Input leakage ≤ ±10 nA.
13 IN1 input Logic control input for channel 1. Drives high to close the switch between NO1 and COM1; low opens it. 1.8-V CMOS compatible with 3-V VCC. Input leakage ≤ ±10 nA.
14 VCC power_in Positive supply voltage, 1.6 V to 3.6 V single-supply operation (absolute max 4 V). Typical ICC is 0.05 µA. Decoupling with a 0.1-µF ceramic capacitor to GND is recommended.
