DG441LEDQ-T1-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441LEDQ-T1-GE3 is a monolithic quad single-pole-single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features a normally closed configuration and operates on single supplies from 3 V to 16 V or dual supplies from ± 3 V to ± 8 V. The device provides low on-resistance of 16 Ω typical, fast switching times with turn-on/turn-off delays up to 70 ns maximum, and low charge injection under 8 pC. Packaged in a 16-lead TSSOP, it supports an operating temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Normally closed SPST configuration for signal routing
• Low parasitic capacitance and charge injection
• TTL and CMOS logic compatible inputs
• High off-isolation and crosstalk performance

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems
• Sample-and-hold circuits
• ADC input circuit designs
• Automatic test equipment
• Process control and automation

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package suffix 'DQ' corresponds to the 16-lead TSSOP form factor required for the target PCB layout. Confirm that the tape and reel packaging format aligns with automated assembly capabilities. Ensure the component meets RoHS compliance standards as indicated by the 'E3' designation before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally closed state is required upon power-up or logic initialization. Compare the 16 Ω on-resistance against load requirements to ensure acceptable voltage drop. Verify that the 70 ns maximum switching speed satisfies the system timing constraints. Consider the ± 8 V dual supply limit if higher voltage isolation is needed.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG441LE family, which includes variants like the DG442LE featuring a normally open configuration. The 'LEDQ' suffix specifically denotes the lead-free, 16-lead TSSOP package variant. The '-T1' suffix indicates the device is supplied in a tape and reel format suitable for surface-mount technology assembly lines.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements within the same family include the DG442LEDQ-T1-GE3, which offers identical electrical characteristics but utilizes a normally open configuration instead of normally closed.
