DG444DY-T1-E3

Overview

The DG444DY-T1-E3 is a quad SPST CMOS analog switch manufactured by Vishay Siliconix, housed in a 16-pin narrow SOIC package. It operates on single supplies from +5 V to +36 V or dual supplies from ±5 V to ±20 V. The device features a maximum drain-source on-resistance of 85 Ω at room temperature and up to 100 Ω across the full operating range. Typical turn-on time is 120 ns with a maximum of 250 ns under dual supply conditions. Power consumption is extremely low, typically 22 nW. The component supports an analog signal range matching the supply rails and includes internal clamp diodes for input protection.

Feature Summary

High-speed switching with minimized charge injection suitable for sample-and-hold circuits
Low power consumption and reduced pedestal errors
TTL/CMOS logic compatible interface
Epitaxial layer design prevents latchup

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the tape-and-reel packaging format associated with the T1 designation. Ensure the E3 suffix indicates compliance with applicable environmental standards as defined in the official datasheet. Cross-reference the part number with the latest Vishay revision history to confirm availability status and any potential product change notifications affecting the component specifications.

Selection Notes

Select this component when upgrading legacy DG211 or DG212 sockets due to its improved speed and lower power characteristics. Verify that the required on-resistance and leakage current specifications align with the provided electrical tables for the intended supply voltage configuration. Confirm that the logic input thresholds are compatible with the system's control voltage levels to ensure reliable switching operation.

Part Context

This part belongs to the DG444/DG445 family of monolithic quad analog switches. The DG444 variant specifically provides a normally closed function, distinguishing it from the DG445 which offers a normally open configuration. Both devices utilize Vishay Siliconix’s high-voltage silicon-gate process to achieve superior switching performance and high-voltage ratings within the same package footprint.
