Overview
The DG442DY-T1 is a CMOS analog switch IC manufactured by Vishay Siliconix, housed in a 16-pin SOIC surface-mount package. It integrates four independent single-pole single-throw (SPST) channels. The device operates with a dual supply voltage of ±15 V and supports single supply configurations. Key electrical parameters include a maximum on-resistance of 85 Ohms, a maximum power dissipation of 900 mW, and a maximum supply current of 100 uA. Switching performance features a maximum turn-on time of 250 ns and a maximum turn-off time of 120 ns. The component functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent SPST analog switches in a compact SOIC-16 package
- Supports both single and dual power supply configurations for flexible system design
- CMOS technology ensures low power consumption and high input impedance
Applications
- Data acquisition systems requiring signal routing
- Industrial process control signal conditioning
- Audio signal switching applications
Procurement Notes
Verify the specific suffix T1 indicates reel packaging when sourcing. Confirm RoHS compliance status through official datasheets as requirements vary by region. Check for obsolescence notices from Vishay Siliconix prior to finalizing procurement plans due to potential lifecycle changes.
Selection Notes
Select this component for designs requiring four isolated analog paths with moderate speed requirements. Ensure the system voltage does not exceed the ±15 V dual supply limit. Verify that the 85 Ohm on-resistance meets the signal integrity requirements of the application circuit.
Part Context
This part belongs to the DG series of analog switches from Vishay Siliconix. It shares functional similarities with other models in the family but differs in channel count, package type, and specific electrical characteristics such as on-resistance and switching speed.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Vishay Siliconix technical support or authorized distributors for verified cross-reference options.
