DG406DW-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG406DW-E3 is a 16-channel single-ended analog multiplexer manufactured by Vishay Siliconix. It connects one of sixteen inputs to a common output based on a 4-bit binary address. The device operates with a maximum supply voltage of 44 V, supporting both single (5 V to 44 V) and dual (±5 V to ±20 V) power supplies. Key electrical parameters include a typical on-resistance of 50 Ω, a maximum transition time of 350 ns at room temperature, and a charge injection of 15 pC. It features TTL-compatible control inputs and an enable function for stacking multiple devices.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents momentary shorting of inputs during channel transitions.
• TTL-compatible digital control inputs ensure compatibility across the full specified operating temperature range.
• Enable (EN) function allows resetting all switches to the off state for stacking multiple devices.
• Epitaxial layer design prevents latchup under high-voltage conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the suffix 'E3' confirms lead-free and RoHS compliance as per Vishay documentation. Confirm the package type matches the wide-body SOIC-28 specification. Ensure the ordering code aligns with the specific temperature range requirements for your application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a 16-channel single-ended configuration is required. Verify that the 44 V absolute maximum rating meets the system's voltage headroom needs. Consider the 50 Ω on-resistance and 15 pC charge injection specifications against signal integrity requirements for precision applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG406/DG407 family of high-performance CMOS analog multiplexers. The DG406 variant specifically provides 16 single-ended channels, whereas the DG407 offers 8 differential channels. Both share the same 44 V silicon-gate CMOS process technology and pinout compatibility within their respective configurations.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum supply voltage rating for the DG406?

The absolute maximum voltage rating is extended to 44 V, allowing operation with supplies up to ±20 V or a single 44 V supply.

How does the DG406 prevent input shorting during switching?

It utilizes break-before-make switching action, which ensures that the previous channel disconnects before the new channel connects, preventing momentary shorting of inputs.

Is the DG406 compatible with TTL logic levels?

Yes, all control inputs, address lines (Ax), and the enable (EN) pin are TTL compatible over the full specified operating temperature range.
