DG444DVZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG444DVZ-T is a monolithic CMOS analog switch manufactured by Renesas Electronics Corporation. It integrates four independent single-pole single-throw (SPST) switches within a compact surface-mount package. The device supports dual power supplies ranging from ±5 V to ±20 V, or a single supply from 5 V to 34 V. Key electrical specifications include a maximum on-resistance of 85 Ohms and a maximum operating frequency of 1 MHz. The component operates reliably across an extended temperature range from -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DVZ-T' against official Renesas documentation to confirm the TSSOP-16 package and tape-and-reel shipping configuration. Ensure that the moisture sensitivity level and lead-free status align with current project requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with moderate on-resistance. Compare against the DG411 series if lower on-resistance is necessary, or the DG442 series if different switching logic polarity is preferred. Confirm voltage headroom meets the application's signal swing requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG44x family of high-voltage CMOS analog switches. It serves as a functional equivalent to legacy devices like the DG211 and DG212, offering improved performance through modern silicon-gate processing techniques while maintaining pin compatibility for drop-in replacements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG442DYZ and DG445DVZ are documented variants within the same product family. Verify package dimensions and logic polarity differences before substituting these parts in existing designs.
