DESCRIPTION
DG381A_MIL DG390A_MIL monolithic CMOS analog switches were designed applications instrumentation, communications, process control. This series suited applications requiring fast switching nearly flat on-resistance over entire voltage range. Designed Vishay Siliconix' PLUS-40 CMOS process, these devices achieve power consumption (3.5 typical) excellent on/off switch performance. These switches ideal battery powered applications, without sacrificing switching speed. Break-before-make switching action guaranteed, epitaxial layer prevents latchup. Single supply operation allowed connecting rail Each switch conducts equally well both directions when blocks supply voltage when off. These switches CMOS quasi logic compatible.

APPLICATIONS
DG381A_MIL DG390A_MIL analog switches will switch positive analog signals while using single positive supply. This allows their applications where only supply available. trade-offs performance given while using single supplies are: increased rDS(on), slower switching speed. Typical curves designing with single supplies supplied (see Typical Characteristics). analog voltage should above below supply voltages which single operation integrator Figure controls discharge rate capacitor that pulsed continuous current ratings exceeded. During reset closed open. Opening with also open will hold integrator output present value.
