DG308A, DG309

Vishay Siliconix

Quad Monolithic SPST CMOS Analog Switches

DESCRIPTION

FEATURES

•

15 V analog input range

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.

Low on-resistance: 60 

Fast switching: 130 ns

Low power dissipation: 30 nW

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.

• CMOS logic compatible

BENEFITS

•

Full rail-to-rail analog signal range

Low signal error

The DG308B, DG309B upgrades are recommended for new

designs.

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
