DG201HSDY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201HSDY is a high-speed quad SPST CMOS analog switch manufactured by Vishay Siliconix. It features four independent switches in a 16-pin Narrow SOIC package, designed for high voltage ratings and superior switching performance using a proprietary silicon-gate process with an epitaxial layer to prevent latchup. The device supports single or dual supply voltages ranging from 4.5 V to 25 V (single) or ±4.5 V to ±22 V (dual). Key electrical parameters include a maximum on-resistance of 50 Ω at room temperature, turn-on time of 60 ns, and turn-off time of 50 ns under dual supply conditions. It operates within a temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'D' indicates the -40 °C to +85 °C operating temperature range and 'Y' denotes the 16-pin Narrow SOIC package. Confirm RoHS compliance status based on the suffix '-E3' if lead-free terminations are required, as standard versions may not be compliant. Ensure the design accounts for the specified power dissipation derating factors above 75 °C.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-speed switching and low on-resistance are critical for the application. The DG201HSDY is suitable for replacing older HI201HS or ADG201HS designs. Consider the 50 Ω on-resistance limit and 30 mA continuous current rating to ensure compatibility with the load requirements. Verify that the input logic levels align with the TTL/CMOS compatibility specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG201HSDY belongs to the DG201HS family of high-speed quad SPST analog switches. This series is engineered to provide fast switching speeds and low error switching of analog signals. The 'DG201HS' designation refers to the general product line, while the full part number specifies the package type and temperature grade.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly documented replacements include the DG201HSDJ (Plastic DIP), DG201HSDQ (TSSOP), and their Pb-free variants ending in '-E3'. Legacy equivalents such as the HI201HS and ADG201HS can be upgraded to this device for space savings and improved performance.
