SGMICRO · Analog Switches, Multiplexers · TSSOP-16

SGM5018YTS from SGMICRO, in a TSSOP-16. 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. Selects whether COMx pins connect to NOx (IN = high) or NCx (IN = low) when EN is low. TTL/CMOS compatible; VIH = 1.6 V, VIL = 0.5 V at V+ = 4.5-5.5 V (VIL = 0.4 V at V+ = 2.7-3.6 V).
2 NC1 passive Channel 1 Normally Closed switch terminal. Analog signal range 0 V to V+; continuous current on NO/NC/COM limited to ±100 mA. Connected to COM1 when EN = low and IN = low.
3 NO1 passive Channel 1 Normally Open switch terminal. Analog signal range 0 V to V+; continuous current on NO/NC/COM limited to ±100 mA. Connected to COM1 when EN = low and IN = high.
4 COM1 passive Channel 1 Common switch pole. Routes to NO1 or NC1 depending on IN state (with EN = low). Typical on-resistance 4.5 Ω at V+ = 4.5 V, ±100 mA.
5 NC2 passive Channel 2 Normally Closed switch terminal. Analog signal range 0 V to V+; continuous current on NO/NC/COM limited to ±100 mA. Connected to COM2 when EN = low and IN = low.
6 NO2 passive Channel 2 Normally Open switch terminal. Analog signal range 0 V to V+; continuous current on NO/NC/COM limited to ±100 mA. Connected to COM2 when EN = low and IN = high.
7 COM2 passive Channel 2 Common switch pole. Routes to NO2 or NC2 depending on IN state (with EN = low). Typical on-resistance 4.5 Ω at V+ = 4.5 V, ±100 mA.
8 GND power_in Ground reference for the device. Analog signals on NO/NC/COM are referenced to GND; V+ is measured relative to GND (-0.3 V to +6 V absolute maximum).
9 COM3 passive Channel 3 Common switch pole. Routes to NO3 or NC3 depending on IN state (with EN = low). Typical on-resistance 4.5 Ω at V+ = 4.5 V, ±100 mA.
10 NO3 passive Channel 3 Normally Open switch terminal. Analog signal range 0 V to V+; continuous current on NO/NC/COM limited to ±100 mA. Connected to COM3 when EN = low and IN = high.
11 NC3 passive Channel 3 Normally Closed switch terminal. Analog signal range 0 V to V+; continuous current on NO/NC/COM limited to ±100 mA. Connected to COM3 when EN = low and IN = low.
12 COM4 passive Channel 4 Common switch pole. Routes to NO4 or NC4 depending on IN state (with EN = low). Typical on-resistance 4.5 Ω at V+ = 4.5 V, ±100 mA.
13 NO4 passive Channel 4 Normally Open switch terminal. Analog signal range 0 V to V+; continuous current on NO/NC/COM limited to ±100 mA. Connected to COM4 when EN = low and IN = high.
14 NC4 passive Channel 4 Normally Closed switch terminal. Analog signal range 0 V to V+; continuous current on NO/NC/COM limited to ±100 mA. Connected to COM4 when EN = low and IN = low.
15 EN input Digital enable control (active-low). Normally connect to GND for switch operation; drive to logic high to force all four switches OFF (all NO/NC disconnected from COM). TTL/CMOS compatible.
16 V+ power_in Positive power supply, 1.8 V to 5.5 V single supply. Absolute maximum 6 V referenced to GND. Supply current typically <1 µA. Bypass with 0.1 µF to GND.
