DG9432, DG9433, DG9434 Vishay Siliconix Low-Voltage Dual SPST Analog Switch DESCRIPTION FEATURES The DG9432, DG9433, DG9434 is a dual single-pole/single- Wide operation voltage (+ 2.7 V to + 12 V) throw monolithic CMOS analog switch designed for high Low charge injection - Q : 1 pC INJ performance switching of analog signals. Combining low Low power consumption power, high speed (t : 25 ns, t : 20 ns), the DG9432, ON OFF TTL/CMOS logic compatible over the full DG9433, DG9434 is ideal for portable and battery powered operating voltage range applications requiring high performance and efficient use of Available in MSOP-8 and SOT23-8 board space. Compliant to RoHS Directive 2002/95/EC The DG9432, DG9433, DG9434 is built on Vishay Siliconixs low voltage BCD-15 process. An epitaxial layer prevents BENEFITS latchup. Break-before-make is guaranteed for DG9432, Reduced power consumption DG9433, DG9434. Simple logic interface High accuracy Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off. Reduce board space APPLICATIONS Battery operated systems Portable test equipment Sample and hold circuits Cellular phones Communication systems Military radio PBX, PABX guidance and control systems FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION - DG9432 DG9432, SOT23-8 DG9432, MSOP-8 NC COM NC V+ 1 1 1 1 8 1 8 V+ IN COM IN 1 1 1 2 7 2 7 IN GND IN COM 2 2 2 3 6 3 6 COM NC GND NC 2 2 2 4 5 4 5 Top View Top View Device Marking: 9432 Device Marking: 4G TRUTH TABLE DG9432 Logic Switch 0On 1Off Document Number: 72311 www.vishay.com S11-1029-Rev.
