DG309 Datasheet | Vishay

DG308A, DG309 Vishay Siliconix Quad Monolithic SPST CMOS Analog Switches DESCRIPTION Featuring low on-resistance (60 ) and fast switching (130 ns), the DG308A is supplied in the “normally open” configuration while DG309 is supplied “normally closed”. Input thresholds are high voltage CMOS patible. Designed with the Vishay Siliconix PLUS-40 CMOS process to bine low power dissipation with a high breakdown voltage rating of 44 V, each switch conducts equally well in both directions when on, and blocks up to the supply voltage when off. An epitaxial layer prevents latch up. The DG308B, DG309B upgrades are remended for new designs.
