DG381B/384B/387B/390B Vishay Siliconix CMOS Analog Switches 15-V Input Range Full Rail-to-Rail Analog Signal Range Low Level Switching Circuits Low r : 30 Minimizes Signal Error Programmable Gain Amplifiers DS(on) Single Supply Operation Low Power Dissipation Portable and Battery Powered Sytems Pin and Function Compatible with the JFET DG180 Family The DG381BDG390B series of monolithic CMOS analog switches are ideal for battery powered applications, without switches was designed for applications in instrumentation, sacrificing switching speed. Break-before-make switching communications, and process control. This series is suited for action is guaranteed, and an epitaxial layer prevents latchup. applications requiring fast switching and nearly flat Single supply operation is allowed by connecting the V rail to on-resistance over the entire voltage range. 0 V. Designed on Vishay Siliconix PLUS-40 CMOS process, Each switch conducts equally well in both directions when on, these devices achieve low power consumption (3.5mW and blocks up to the supply voltage when off. These switches typical) and excellent on/off switch performance. These are CMOS and quasi TTL logic compatible.
