DG409DQ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG409DQ-E3 is a dual 4-channel differential analog multiplexer manufactured by Vishay Siliconix in a 16-pin TSSOP surface-mount package. It operates on single supplies from +5 V to +36 V or dual supplies from ±5 V to ±20 V. The device features a maximum drain-source on-resistance of 100 Ω, a transition time of 160 ns, and charge injection of 20 pC. Control inputs are TTL compatible, and the unit supports an operating temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents momentary crosstalk between adjacent channels.
• TTL-compatible logic control inputs simplify interface with digital systems.
• Epitaxial layer construction prevents latchup for improved reliability.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix 'E3' confirms lead-free and RoHS compliance status. Confirm the 'DQ' suffix matches the required 16-lead TSSOP package dimensions. Ensure the component meets the specified commercial temperature range requirements for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a dual differential 4:1 multiplexer configuration is required. Verify that the 100 Ω on-resistance and 160 ns transition time meet system bandwidth and speed constraints. Ensure the supply voltage range aligns with the available power rails in the design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG408/DG409 family of high-performance CMOS analog multiplexers. While the DG408 provides an 8-channel single-ended configuration, the DG409 offers two independent 4-channel differential paths. Both share identical electrical characteristics and pinouts within their respective configurations.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the DG409 handle channel switching?

It utilizes break-before-make switching action to prevent momentary crosstalk between adjacent channels during transitions.

What is the maximum absolute voltage rating?

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

Can the device operate with a single supply?

Yes, the device supports single supply operation ranging from +5 V to +36 V.
