DESCRIPTION
DG381A-DG390A series monolithic CMOS analog switches designed applications instrumentation, communications, process control. This series suited applications requiring fast switching nearly flat on-resistance over entire voltage range. battery powered applications, without sacrificing switching speed. Break-before-make switching action guaranteed, epitaxial layer prevents latchup. Single supply operation allowed connecting rail
Designed Vishay Siliconix' PLUS-40 CMOS process, these devices achieve power consumption (3.5 typical) excellent on/off switch performance. These switches ideal
Each switch conducts equally well both directions when blocks supply voltage when off. These switches CMOS quasi logic compatible.

APPLICATIONS
DG381A series 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
