DG441DJ-E3

Overview

The DG441DJ-E3 is a quad single-pole single-throw (SPST) normally closed CMOS analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of ±5 V to ±20 V for dual supplies, or 5 V to 36 V for single supplies. The device features a typical drain-source on-resistance of 50 Ω and a maximum turn-on time of 250 ns. Built on a high-voltage silicon-gate process with an epitaxial layer, it prevents latchup and supports signals up to the supply rails. The component is housed in a 16-pin plastic DIP package and complies with RoHS standards.

Feature Summary

Normally closed logic configuration
TTL/CMOS-compatible digital control interface
Latchup-proof construction via epitaxial layer
Low charge injection suitable for sample-and-hold circuits

Applications

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

Procurement Notes

Verify the specific suffix 'E3' confirms lead-free compliance and material categorization requirements. Confirm the 'D' designation corresponds to the 16-pin plastic DIP package variant. Ensure the ordering code matches the required temperature range of -40 °C to +85 °C. Cross-reference the manufacturer part number against current datasheet revisions to validate functional specifications.

Selection Notes

Select this component when a normally closed state is required upon power-up or logic low input. The DG441DJ-E3 serves as a direct upgrade path for legacy DG201A sockets. Evaluate the 50 Ω on-resistance and 250 ns switching speed against system timing constraints. Verify that the ±20 V dual supply capability meets the dynamic range requirements of the analog signals being routed.

Part Context

This device belongs to the DG441/DG442 family of monolithic quad analog switches. The DG441 variant specifically provides a normally closed function, contrasting with the DG442's normally open configuration. Both share identical electrical characteristics and are designed for high-speed, low-error switching of analog and audio signals using Vishay Siliconix's high-voltage silicon-gate process technology.
