DESCRIPTION
Featuring low on-resistance (60 Q) and fast switching
(130 ns), the DG308A is supplied in the "normally open"
conhguration while DG309 is supplied "normally closed." Input
thresholds are high voltage CMOS compatible.
Designed with the Vishay Siliconix PLUS-4O 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.

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 O V.
