High Voltage 4 Quad SPST CMOS Analog Switch
DESCRIPTION
The DG454 series has four independently selectable high
voltage (44 V) SPST switches, each with a typical on
resistance of 4 and a typical flatness of 0.2 , ideal
parameters for low distortion audio signal switching.
The DG454 (NC) and DG455 (NO) are identical except for
the digital logic control input, which is inverted as shown in
the Truth Table. The DG456 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.
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 DG454 DG455 and DG456 are pin compatible with the
DG411, DG412 and DG413, except they require no V
L
supply.
