COS12A12511

COSINE · Analog Switches / Multiplexers · MSOP-8

COS12A12511 from COSINE, in a MSOP-8. 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 COM bidirectional Common analog terminal of the SPDT switch. Bidirectional analog I/O; connects to either NC (when IN=L) or NO (when IN=H). Signal range V- to V+.
2 NC bidirectional Normally-closed analog terminal. Bidirectional analog I/O connected to COM when logic control IN is LOW. Signal range V- to V+.
3 GND power_in Ground, 0 V reference for the logic input and switch circuitry.
4 V+ power_in Most positive power supply. +3 V to +16 V (single supply, COS12A12511S) or +3 V to +8 V (dual supply, COS12A12511). Sets the upper analog signal rail.
5 N.C. unconnected No connect. Not internally connected; leave floating or tie to any convenient net.
6 IN input Digital logic control input selecting the switch throw. IN=LOW connects COM to NC; IN=HIGH connects COM to NO. TTL/CMOS compatible (VIL ≤ 0.8 V, VIH ≥ 2.4 V at 5 V supply).
7 V- power_in Most negative power supply. Used only in dual-supply applications (down to -8 V for COS12A12511); must be tied to GND for single-supply operation (COS12A12511S).
8 NO bidirectional Normally-open analog terminal. Bidirectional analog I/O connected to COM when logic control IN is HIGH. Signal range V- to V+.
