Overview
The DG441BDY-T1 is a monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix in a 16-pin narrow SOIC package. It operates on single or dual supplies, with a maximum supply voltage of 36 V (single) or ±18 V (dual). The device features a typical on-resistance of 45 Ω and a maximum of 80 Ω at room temperature. Switching times are specified as 220 ns for turn-on and 120 ns for turn-off. Power consumption is low at 1 mW, with a maximum supply current of 1 µA. The operating temperature range spans from -40 °C to +85 °C.
Feature Summary
- Low on-resistance minimizes signal errors and distortion
- Fast switching action enables faster system throughput
- Low charge injection reduces pedestal errors in sample-and-hold circuits
- TTL/CMOS-compatible logic allows simple interfacing
Applications
- Audio switching
- Data acquisition systems
- Sample-and-hold circuits
- Communication systems
- Automatic test equipment
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and compliance status. Confirm that the component meets all required environmental and electrical specifications for the intended application before procurement.
Selection Notes
Select this component when low on-resistance and fast switching speeds are required for analog signal routing. Ensure the supply voltage and power dissipation limits accommodate the thermal requirements of the specific PCB layout and operating environment.
Part Context
This part belongs to the DG441B/DG442B family of improved quad SPST CMOS analog switches. It serves as an upgrade to the original DG441/DG442 models, offering enhanced performance characteristics while maintaining compatibility with existing designs requiring high-speed analog switching.
Replacement Considerations
DG441BDY-T1-E3: Same functional specifications with RoHS compliance. DG441DY-T1-E3: Higher on-resistance (85 Ω max), slower switching (250 ns), higher supply current (100 µA). DG441LDQ-T1-E3: TSSOP-16 package, lower power dissipation (450 mW).
