Product details

Crosstalk and signal integrity

Channel-to-channel crosstalk is rated at -100 dB at 1 MHz.

Temperature range and environment

Rated for -40°C to 85°C ambient, the DG444DY+ fits industrial control cabinets, outdoor telecom shelters, and test equipment that sees seasonal temperature swings. The 16-SOIC footprint is a common surface-mount package, so board layout and rework are straightforward.

Sourcing and lifecycle

The DG444DY+ carries an active lifecycle status and is ROHS3 compliant. For a BOM line that needs a reliable quad SPST-NC switch, this part is a safe choice for new designs and ongoing production.

Frequently asked questions

What is the crosstalk rating of DG444DY+?

Channel-to-channel crosstalk is -100 dB at 1 MHz, providing strong isolation between the four switch channels for precision analog multiplexing.

What package does DG444DY+ come in?

It is supplied in a 16-SOIC surface-mount package (0.154" body width, 3.90 mm). The shipping medium is Tube.

Can DG444DY+ run on a single supply?

Yes, it accepts a single supply from 10 V to 30 V, or a dual supply from ±4.5 V to ±20 V. That covers common industrial rails like +12 V, +24 V, or ±15 V.
