DG411LDJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411LDJ-E3 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features four independent channels in a 16-pin PDIP package with through-hole mounting. The device operates on dual supplies ranging from ±15 V to ±15 V, supporting a total supply range of 30 V. Key electrical parameters include a maximum on-resistance of 80 Ohms, a maximum power dissipation of 900 mW, and a maximum supply current of 1 µA. Switching performance specifies a maximum turn-on time of 85 ns and a maximum turn-off time of 60 ns. The component supports a DC switch current of 30 mA and functions within an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Four independent SPST analog switches integrated into a single monolithic CMOS device.
• High-voltage silicon gate process construction providing latch-up protection via an epitaxial layer.
• Bidirectional signal conduction capability allowing identical performance in both directions when turned on.
• Break-before-make switching action ensures isolation between channels during state transitions.

Analog Switches, Multiplexers, Demultiplexers Applications

• Industrial control systems requiring high-voltage signal routing
• Test and measurement equipment for precision analog signal switching
• Communication and network infrastructure signal path management

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the obsolete status of this component before design finalization, as distribution availability may be limited. Confirm that the PDIP-16 through-hole package aligns with the target PCB footprint and assembly processes. Ensure the 80 Ohm on-resistance meets the specific application's voltage drop requirements compared to lower-resistance alternatives in the same series.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a through-hole PDIP-16 package is required for the quad SPST configuration. Compare the 80 Ohm on-resistance against the 33 Ohm variants available in surface-mount packages if lower insertion loss is critical. Verify that the ±15 V dual supply requirement fits the system power architecture, as single-supply operation limits are not specified for this specific leaded variant in the provided data.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG series of analog switches from Vishay Siliconix. It shares the core quad SPST functionality with other members like the DG411DY-E3 but differs in packaging and specific electrical characteristics due to the through-hole construction. The suffix E3 indicates compliance with specific environmental standards regarding restricted substances.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411LDY-E3 offers similar quad SPST functionality in a surface-mount SOIC-16 package with improved switching speeds (50 ns/35 ns) and lower on-resistance (33 Ohms). Designers must account for the package change from PDIP to SOIC and verify thermal dissipation differences.
