Overview
The DG441DYZ-T is a monolithic CMOS analog switch manufactured by Renesas Electronics Corporation, housed in a 16-lead SOIC-Narrow package. It integrates four independent single-pole single-throw (SPST) normally closed switches. The device supports single supply voltages from 5 V to 34 V or dual supplies from ±5 V to ±22 V. Key electrical specifications include a maximum on-resistance of 85 Ohms, a maximum turn-on time of 250 ns, and a maximum turn-off time of 120 ns. It operates within a temperature range of -40°C to +85°C and features a maximum power dissipation of 1.6 mW.
Feature Summary
- Integrates four independent SPST analog switches with normally closed logic configuration
- Utilizes high-voltage silicon-gate process for latch-up prevention and low charge injection
- Supports both single-ended and split power supply configurations for flexible system design
Applications
- Sample and hold circuits requiring normally closed signal paths
- Data acquisition systems with multi-channel input selection
- Automatic test equipment for signal routing
- Communication systems for analog signal switching
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure moisture sensitivity level requirements are addressed during storage and handling procedures to maintain component integrity throughout the assembly process.
Selection Notes
Select this component when a normally closed SPST configuration is required for analog signal routing. Compare against the DG442DYZ for normally open alternatives. Evaluate the 85 Ohm on-resistance limit against circuit impedance requirements. Consider the 250 ns switching speed for timing-sensitive applications within the industrial temperature range.
Part Context
This part belongs to the DG441 series of monolithic CMOS analog switches. It serves as an upgrade to older DG211/DG212 technologies, offering improved switching speeds and reduced charge injection. The device is designed for drop-in replacement in existing designs while providing enhanced performance characteristics for modern data acquisition and signal processing applications.
Replacement Considerations
The DG442DYZ offers identical electrical specifications but utilizes normally open logic instead of normally closed. Verify logic polarity requirements before substitution. Other family members like DG411 provide lower on-resistance but differ in voltage ratings and switching speeds.
