Vishay Siliconix
High Voltage 4-Ω Quad SPST CMOS Analog Switch
DESCRIPTION
FEATURES
The DG454 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.

COMPLIANT
44 V supply maximum rating
15 V analog signal range
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.
Fully specified at supply voltages of 5 V, 12 V and 15 V
No VL required
Fast switching speed:
- ton 80 ns
- toff 60 ns
TTL/CMOS compatible
ESD protection 2 kV
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.
• Pin compatible with DG411, DG412, and DG413, except
no VL required
