DG444DVZ

Overview

The DG444DVZ is a monolithic CMOS analog switch manufactured by Renesas Electronics Corporation. It integrates four independent single-pole single-throw (SPST) switches in a 16-pin TSSOP package. The device supports single or split supply operation with voltage ranges of 5V to 34V for single supply and ±5V to ±20V for dual supply. Key electrical parameters 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 low power consumption.

Feature Summary

Features four independent SPST analog switches with TTL and CMOS compatible digital inputs.
Utilizes high-voltage silicon-gate process technology to prevent latch-up issues associated with older CMOS technologies.
Provides fast switching action and reduced charge injection, simplifying sample and hold applications.
Offers bilateral switches that are equally matched for AC or bidirectional signals.

Applications

Audio switching systems
Data acquisition circuits
Sample and hold circuits
Automatic test equipment

Procurement Notes

Verify the specific suffix 'DVZ' corresponds to the TSSOP-16 package and industrial temperature grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure handling procedures account for moisture sensitivity levels specified in the component data sheet.

Selection Notes

Select the DG444DVZ when drop-in replacement for DG211/DG212 series devices is required with improved speed and lower resistance. Choose this model over DG445 variants if the specific selection logic polarity matches the design requirements. Verify that the 85 Ohm on-resistance meets the signal integrity needs of the application circuit.

Part Context

The DG444DVZ belongs to the DG444/DG445 family of monolithic quad SPST CMOS analog switches. These devices are designed as upgrades to the legacy DG211 and DG212 series, offering enhanced performance characteristics such as faster switching times and lower charge injection while maintaining pin compatibility.

Replacement Considerations

The DG444DVZ serves as a direct upgrade from the DG211 and DG212 series. For alternative packages, the DG444DYZ (SOIC-16) is available within the same functional family. Cross-reference with DG445 series parts only if the logic polarity difference is acceptable for the specific circuit design.

FAQ

How does the DG444DVZ differ from the DG445 series?

The DG444DVZ and DG445 series are identical in terms of analog performance and physical structure, differing only in the polarity of the digital selection logic used to control the switches.
