1 / 11 page Vishay Siliconix DG308A, DG309 Document Number: 70046 S11-0303-Rev. G, 28-Feb-11 www.vishay.com 1 Quad Monolithic SPST CMOS Analog Switches FEATURES • ± 15 V analog input range • Low on-resistance: 60 • Fast switching: 130 ns • Low power dissipation: 30 nW • CMOS logic compatible BENEFITS • Full rail-to-rail analog signal range • Low signal error • Wide dynamic range • Single or dual supply capability • Static protected logic inputs • Space savings (TSSOP) APPLICATIONS • Portable and battery powered instrumentation • Communication systems • Computer peripherals • High-speed multiplexing 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 compatible. Designed with the Vishay Siliconix PLUS-40 CMOS process to combine 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 recommended for new designs.
