Vishay Siliconix

High Voltage 4- Quad SPST CMOS Analog Switch

DESCRIPTION
The DG451 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 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 uW). 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, D
G412, and DG413.
