COS4561TR

The COS4561 is a single- pole/double- throw (SPDT) CMOS analog switch. The COS4514 and COS4515 are single pole / single throw (SPST) CMOS analog switches. They have very low switch ON- state resistance. The COS4514 is normally open (NO). The COS4515 is normally closed (NC). These CMOS switches can operate continuously with a single supply between 3V and 16V. Each switch can handle rail- to- rail analog signals. The OFF/ON- Leakage current maximum is only 1nA at 25℃ or 10nA at 85℃. The digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS logic compatibility when using a +5V supply.
