DG408DY-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG408DY-E3 is an 8-channel single-ended analog multiplexer manufactured by Vishay Siliconix in a 16-pin narrow SOIC package. It connects one of eight inputs to a common output via a 3-bit binary address (A0, A1, A2). The device operates on a single supply from +5 V to +36 V or dual supplies from ±5 V to ±20 V. Key electrical parameters include a maximum drain-source on-resistance of 100 Ω, a transition time of 160 ns, and charge injection of 20 pC. It features TTL-compatible logic inputs and an enable function for stacking multiple devices.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix -E3 confirms lead-free and RoHS compliance status. Confirm the package type matches the narrow SOIC-16 specification. Check the datasheet for material categorization definitions regarding environmental compliance. Ensure the absolute maximum ratings are not exceeded during operation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8:1 single-ended configuration is required. Verify that the 100 Ω maximum on-resistance meets circuit requirements. Ensure the 36 V single supply limit accommodates the application voltage. Consider the 160 ns transition time for signal speed constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG408/DG409 family of high-performance CMOS analog multiplexers. The DG408 provides an 8-channel single-ended path, while the DG409 offers a dual 4-channel differential path. Both utilize a 44 V silicon-gate CMOS process designed for ruggedness and low power dissipation.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the device prevent crosstalk?

It utilizes break-before-make switching action to protect against momentary crosstalk between adjacent channels.

What is the maximum supply voltage rating?

The absolute maximum voltage rating is extended to 44 V due to the 44 V silicon-gate CMOS process.

Can multiple devices be stacked?

Yes, the Enable (EN) function allows the user to reset the multiplexer to all switches off for stacking several devices.
