COSN74LVC1G3157DBVR

COSINE · Analog Switches, Multiplexers · SOT-23-6

COSN74LVC1G3157DBVR from COSINE, 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 NO passive Normally Open switch terminal. Connected to COM when IN is HIGH; disconnected (high impedance) when IN is LOW. Bidirectional analog signal path, 0V to VCC, ~4.5Ω typ. ON-resistance at VCC=5V.
2 GND power_in Ground reference for the device (0V).
3 NC passive Normally Closed switch terminal. Connected to COM when IN is LOW; disconnected (high impedance) when IN is HIGH. Bidirectional analog signal path, 0V to VCC, ~4.5Ω typ. ON-resistance at VCC=5V. Note: 'NC' here means Normally Closed switch pole, not No-Connect.
4 COM passive Common switch terminal (pole). Routed to either NO or NC depending on the IN control state. Bidirectional analog signal path, 0V to VCC.
5 VCC power_in Positive supply voltage, 1.65V to 5.5V (absolute max 6.0V). Typical ICC = 5 μA at 5.5V.
6 IN input Digital control input selecting the switch path. IN=0 connects COM to NC (NO off); IN=1 connects COM to NO (NC off). Must be driven HIGH or LOW; VIH=2.6V (5V supply), VIL=0.8V (5V supply). TTL/CMOS compatible.
