DG441LDY-E3

Overview

The DG441LDY-E3 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of ±15 V and supports both single and dual power configurations. The device features a maximum on-resistance of 33 Ohms, with a typical turn-on time of 60 ns and turn-off time of 35 ns. It is housed in a 16-pin SOIC package designed for surface mount technology. The component functions across an operating temperature range from -40°C to +85°C. Maximum power dissipation is rated at 650 mW, while the maximum supply current is 1 µA. The DC switch current capability is specified at 30 mA.

Feature Summary

Integrates four independent SPST switches in a compact surface-mount package
Supports flexible single or dual power supply configurations
Provides low on-resistance for signal path integrity

Applications

Signal routing in data acquisition systems
Multiplexing in measurement instrumentation
Audio signal switching applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check current lifecycle status as availability may be limited due to end-of-life designations. Ensure packaging specifications match assembly requirements.

Selection Notes

Compare on-resistance values against application signal integrity needs. Evaluate thermal performance based on expected power dissipation limits. Verify package compatibility with existing PCB footprints. Assess switching speed requirements against the 60 ns turn-on specification.

Part Context

This component belongs to the DG series of analog switches from Vishay Siliconix. It serves as a replacement alternative for legacy designs requiring quad SPST functionality. The part number suffix indicates specific packaging and environmental compliance variations within the product family.
