DG406BDW-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG406BDW-E3 is a 16-channel single-ended analog multiplexer manufactured by Vishay Siliconix. It connects one of sixteen inputs to a common output via a 4-bit binary address and operates within a supply voltage range of 5 V to 44 V (single) or ±5 V to ±20 V (dual). The device features a maximum on-resistance of 100 Ω, a transition time of up to 163 ns, and an off-isolation of -86 dB. Packaged in a 28-pin widebody SOIC, it supports TTL-compatible logic inputs and break-before-make switching.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents momentary shorting of inputs during channel transitions.
• TTL-compatible control inputs allow direct interfacing with standard digital logic across the full operating temperature range.
• Enable function allows resetting all switches to the off state for stacking multiple devices.

Analog Switches, Multiplexers, Demultiplexers Applications

• High-speed data acquisition systems
• Audio signal routing and switching

• Medical instrumentation

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the suffix 'E3' confirms lead-free and RoHS compliance status. Confirm the package type matches the required 28-pin widebody SOIC footprint. Ensure the specified operating temperature range meets the application requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a high channel count (16:1) is required in a surface-mount format. Verify that the 100 Ω maximum on-resistance and 163 ns transition time satisfy the system's bandwidth and speed constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG406B/DG407B series of high-performance CMOS analog multiplexers. It is designed using a 44 V silicon-gate CMOS process, which extends absolute maximum voltage ratings and allows operation with dual supplies up to ±20 V.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the purpose of the Enable (EN) pin?

The Enable function allows the user to reset the multiplexer to all switches off, which facilitates stacking several devices together.

How does the device handle input signals exceeding the supply rails?

Signals on the source pins exceeding the power supply rails are clamped by internal diodes. The forward diode current must be limited to the maximum current ratings.

What is the typical charge injection value?

The typical charge injection is 11 pC under standard test conditions.
