A, 22-Jan-01 www.vishay.com 1 CMOS Analog Switches FEATURES BENEFITS APPLICATIONS D "15-V Input Range D Low rDS(on): 30 W D Single Supply Operation D Pin and Function Compatible with the JFET DG180 Family D Full Rail-to-Rail Analog Signal Range D Minimizes Signal Error D Low Power Dissipation D Low Level Switching Circuits D Programmable Gain Amplifiers D Portable and Battery Powered Sytems DESCRIPTION The DG381B–DG390B series of monolithic CMOS analog switches was designed for applications in instrumentation, communications, and process control. This series is suited for applications requiring fast switching and nearly flat on-resistance over the entire voltage range. Designed on Vishay Siliconix’ PLUS-40 CMOS process, these devices achieve low power consumption (3.5 mW typical) and excellent on/off switch performance. These switches are ideal for battery powered applications, without sacrificing switching speed. Break-before-make switching action is guaranteed, and an epitaxial layer prevents latchup. Single supply operation is allowed by connecting the V– rail to 0 V. Each switch conducts equally well in both directions when on, and blocks up to the supply voltage when off. These switches are CMOS and quasi TTL logic compatible. FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION TRUTH TABLE Logic Switch 0 ON 1 OFF Logic “0” v 0.8 V Logic “1” w 4 V |
