Vishay DG308ADY-T1 Quad monolithic spst cmos analog switch Datasheet

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.

c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

e.Guaranteed by design, not subject to production test.
f. VIN = input voltage to perform proper function.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.

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.
