DG441DY-E3

Overview

The DG441DY-E3 is a quad single-pole single-throw (SPST) normally closed CMOS analog switch manufactured by Vishay Siliconix in a 16-pin narrow SOIC package. It operates on dual supplies ranging from ±5 V to ±20 V or a single supply from 5 V to 36 V. The device features a typical drain-source on-resistance of 50 Ω, with a maximum of 85 Ω at room temperature and 100 Ω across the full operating range. Turn-on time is typically 150 ns, with a maximum of 250 ns. Charge injection is minimized to -1 pC, and off-leakage current is limited to 0.5 nA. The component supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

CMOS logic compatible for simplified interfacing
High-speed switching with low signal distortion
Minimized charge injection suitable for sample-and-hold circuits
Epitaxial layer prevents latchup for high voltage ratings

Applications

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

Procurement Notes

Verify the specific suffix 'E3' confirms RoHS compliance and halogen-free material categorization as defined by Vishay standards. Confirm the 'D' suffix corresponds to the 16-pin narrow SOIC package variant rather than plastic DIP. Ensure the ordering code matches the exact functional requirement for normally closed switches.

Selection Notes

Select this part when a normally closed SPST configuration is required, distinguishing it from the DG442 which is normally open. Evaluate the 50 Ω typical on-resistance against circuit tolerance requirements. Consider the 150 ns turn-on speed for bandwidth limitations in high-frequency applications compared to faster alternatives.

Part Context

This component belongs to the DG441/DG442 family of monolithic quad analog switches. It is designed to upgrade legacy DG201A/DG202 sockets while providing superior performance through Vishay's high-voltage silicon-gate process technology.
