Vishay Siliconix
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 VL supply.

Notes: a. VIN = input voltage to perform proper function. b. Room = 25 C, Full = as determined by the operating temperature suffix. c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet. e. Guaranteed by design, not subject to production test.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
