DG308A/DG309 Vishay Siliconix Quad Monolithic SPST CMOS Analog Switches DESCRIPTION FEATURES Featuring low on-resistance (60 Ω) 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. • ± 15 V Analog Input Range 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/309B upgrades are recommended for new designs.

Switching Time APPLICATIONS Single Supply Operation The DG308A and DG309 will switch positive analog signals while using a single positive supply. This will allow use in many applications where only one supply is available. The trade-offs or performance given up while using single supplies are: 1) increased rDS(on) and 2) slower switching speed. As stated in the absolute maximum ratings section of the data sheet, the analog voltage should not go above or below the supply voltages which in single supply operation are V+ and 0 V.
