DG406DN-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG406DN-T1 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. The device operates with supply voltages up to ±20 V or a single 12 V supply, featuring a maximum rating of 44 V. Key electrical parameters include an on-resistance (RDS(on)) of 50 Ω, charge injection of 15 pC, and transition time of 200 ns. It utilizes a 28-pin PLCC package and supports TTL-compatible control inputs.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents momentary shorting of inputs during channel transitions.
• TTL-compatible digital control inputs allow direct interfacing with standard logic families across the full operating temperature range.
• Epitaxial layer construction ensures latchup immunity under specified voltage conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix requirements for the ordered component. The -T1 designation indicates tape and reel packaging, while -E3 denotes lead-free and RoHS compliance. Confirm that the 28-pin PLCC package variant matches the target PCB footprint and soldering profile specifications before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a high channel count (16:1) is required for single-ended signal routing. Ensure the application supports the specified 50 Ω on-resistance and 44 V absolute maximum voltage rating. Verify that the 28-pin PLCC package dimensions are compatible with the assembly process and available board space constraints.

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 channels, whereas the DG407 offers dual 8-channel differential configurations. Both share similar electrical characteristics and are designed for applications requiring low power dissipation and wide supply ranges.

Analog Switches, Multiplexers, Demultiplexers FAQ

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

The Enable (EN) function allows the user to reset the multiplexer to all switches off, which facilitates stacking several devices in a system.

How does the device handle input signals exceeding supply rails?

Signals on source (SX), drain (DX), or input pins exceeding V+ or V- will be clamped by internal diodes. Forward diode current must be limited to maximum ratings.

What is the break-before-make interval?

The break-before-make interval is typically 50 ns at room temperature and can reach up to 25 ns in the full operating temperature range.
