DG451, DG452, DG453
Vishay Siliconix
High Voltage 4-Ω Quad SPST CMOS Analog Switch
DESCRIPTION
FEATURES
The DG451 series has four independently selectable high
voltage (44 V) SPST switches, each with a typical on
resistance of 4 Ω and a typical flatness of 0.2 Ω, ideal
parameters for low distortion audio signal switching.
The DG451 (NC) and DG452 (NO) are identical except for
the digital logic control input, which is inverted as shown in
the Truth Table. The DG453 has two normally closed and
two normally open switches.
These are high voltage switches that are fully specified with
dual supplies at ± 5 V and ± 15 V and a single supply of
12 V and operating with ultra low power dissipation (18 µW).
Fast switching speeds coupled with high signal bandwidth
makes these parts suitable for video switching applications.
All digital inputs have 0.8 V and 2.4 V logic thresholds
ensuring low voltage TTL/CMOS compatibility. Each switch
conducts equally well in both directions when on and can
handle an input signal range that extends to the supply
voltage rails.
The DG451, DG452, and DG453 are pin compatible with the
DG411, DG412, and DG413.
