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 VL

supply.
