Overview
The DG441DVZ-T is a monolithic quad single-pole single-throw (SPST) normally-closed analog switch manufactured by Renesas Electronics Corporation. It features four independent switches in a 16-TSSOP package with an on-resistance maximum of 85 ohms. The device supports single supply voltages from 5 V to 34 V or dual supplies from ±5 V to ±22 V. Key electrical parameters include a maximum turn-on time of 250 ns, a maximum turn-off time of 120 ns, and a maximum power supply current of 100 uA. It operates within a temperature range of -40°C to +85°C.
Feature Summary
- Four independent SPST normally-closed analog switches integrated into a single monolithic CMOS structure.
- Low power consumption suitable for battery-operated systems with minimal supply current draw.
- TTL and CMOS compatible digital inputs simplify interface logic requirements.
Applications
- Data acquisition systems requiring signal routing
- Sample and hold circuits
- Automatic test equipment
Procurement Notes
Verify the specific suffix 'DVZ-T' corresponds to the 16-TSSOP surface-mount package and tape-and-reel carrier type. Confirm that the component meets RoHS compliance standards and lead-free annealing requirements as specified by the manufacturer. Ensure the ordering information matches the exact part number to avoid discrepancies in packaging or pin configuration.
Selection Notes
Select this component when a normally-closed configuration is required for signal paths. Compare the 85 ohm on-resistance against application tolerance limits. Consider the 250 ns switching speed for timing constraints. Verify that the 34 V single-supply limit accommodates the maximum signal swing without exceeding absolute maximum ratings.
Part Context
This part belongs to the DG441 series of monolithic CMOS analog switches. It serves as a functional alternative to older discrete switch implementations. The device integrates four bilateral switches designed for AC or bidirectional signal handling. It utilizes a high-voltage silicon-gate process to ensure latch-up immunity.
Replacement Considerations
The DG441DYZ-T is a direct replacement offering identical electrical specifications but packaged in a 16-SOIC-Narrow format instead of TSSOP. Designers must verify footprint compatibility during substitution. Other series members like DG442 differ by using normally-open configurations.
