DG449 Vishay Siliconix High Voltage Single SPDT Analog Switch in SOT23-8 DESCRIPTION FEATURES The DG449 is a dual supply single-pole/double-throw • • • • • • (SPDT) switches. On resistance is 38  and flatness is 2.6  max over the specified analog signal range. These analog switches were designed to provide high speed, low error switching of precision analog signals. The primary application areas are in the routing and switching in telecommunications and test equipment. Combining low power, low leakages, low on-resistance and small physical size, the DG449 is also ideally suited for portable and battery powered industrial and military equipment. The DG449 operates either from a single + 7 V to 36 V supply or from dual ± 4.5 V to ± 20 V supplies. It is offered in ± 15 V analog signal range On-resistance - RDS(on): 38 max. VL logic supply not required TTL CMOS input compatible Rail to rail signal handling Dual or single supply operation BENEFITS • • • • • • Wide dynamic range Low signal errors and distortion Break-before-make switching action Simple interfacing Small SOT23-8ld package; reduced board space Improved reliability the very popular, small SOT23-8 package. APPLICATIONS • • • • • • • • Precision test equipment Precision instrumentation Communications systems PBX, PABX systems Audio equipment Redundant systems PC multimedia boards Hard disc drives FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG449 TRUTH TABLE Logic 0 1 NC ON OFF NO OFF ON Logic "0" 0.8 V Logic "1" 2.4 V Document Number: 73897 S11-0097-Rev.
