DG442LDQ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442LDQ-E3 is a quad single-pole single-throw (SPST) analog switch IC manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 3 V to 16 V or dual supplies up to ±8 V. The device features a maximum on-resistance of 140 Ohms, with a maximum power dissipation of 650 mW. Switching performance includes a maximum turn-on time of 210 ns and a maximum turn-off time of 130 ns. It supports a maximum DC switch current of 10 mA and draws a maximum supply current of 1 uA. The component is housed in a 16-pin TSSOP package and functions within an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates four independent SPST analog switches in a compact surface-mount package.
• Supports flexible power configurations with single or dual supply voltage operation.
• Maintains low quiescent supply current for energy-efficient circuit designs.

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in data acquisition systems
• Multiplexing sensor inputs
• Audio signal switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'LDQ' corresponds to the TSSOP-16 package variant when sourcing replacements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 140 Ohm on-resistance limits for the target application signals.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with moderate on-resistance specifications. Compare against the DG442LEDY-GE3 for SOIC-16 packaging alternatives. Evaluate the DG442LDY-E3 if lower on-resistance and faster switching speeds are necessary for high-performance applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG44x series of CMOS analog switches from Vishay Siliconix. The series provides multiple channel counts and package options for general-purpose signal switching. The DG442 specifically offers four channels, distinguishing it from dual-channel or octal variants within the same product family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG442LEDY-GE3 serves as a direct pin-compatible alternative in a SOIC-16 package. Designers requiring lower on-resistance should consider the DG442LDY-E3, though it may have different availability status.
