DG412HSDY-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412HSDY-E3 is a precision monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It features four independent switches in a 16-pin SOIC package, designed for high-speed signal routing with low error characteristics. The device operates on dual supplies ranging from ±5 V to ±20 V or single supplies up to 44 V. Key electrical parameters include a maximum on-resistance of 35 Ω at ±15 V, turn-on time of 105 ns, and turn-off time of 80 ns. It supports an analog signal range of ±15 V, draws a maximum supply current of 1 µA, and functions within a temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• High-voltage silicon gate process construction with epitaxial layer preventing latchup
• Break-before-make switching action to prevent signal shorting during transitions
• TTL and CMOS logic compatible control interface
• Bidirectional conduction when active and voltage blocking up to supply levels when inactive

Analog Switches, Multiplexers, Demultiplexers Applications

• Precision automatic test equipment
• Precision data acquisition systems
• Communication systems
• Battery powered industrial applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E3' confirms lead-free and RoHS compliance status as defined by Vishay. Confirm the 'D' suffix indicates the narrow SOIC-16 package variant suitable for surface mount assembly. Ensure the operating environment remains within the specified -40 °C to +85 °C temperature range to maintain guaranteed electrical performance limits.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component over the DG411HS equivalent due to its inverted logic control scheme where Logic 0 activates the switch. Verify that the 35 Ω maximum on-resistance meets the signal integrity requirements for the target application. Ensure the power dissipation rating of 600 mW in the SOIC package accommodates the thermal load under maximum operating conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411HS/DG412HS/DG413HS family of precision analog switches. The DG412HS specifically provides four normally open switches controlled by inverted logic compared to the DG411HS. The DG413HS variant combines two normally open and two normally closed switches. All variants share the same high-voltage silicon gate process technology.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG411HSDY-E3: Electrically identical but utilizes non-inverted logic control (Logic 1 turns switch ON). DG412LEDY-GE3: Lower voltage rating (max 16V) and higher on-resistance (140 Ohms), not suitable for high-voltage applications.
