DG407DN-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG407DN-T1-E3 is a dual 8-channel high-performance CMOS analog multiplexer manufactured by Vishay Siliconix. It selects one of eight differential input pairs to a common differential output using a 3-bit binary address. The device operates with supply voltages ranging from ±5 V to ±20 V, or a single supply up to 44 V. Key electrical parameters include a maximum on-resistance of 125 Ω and a typical charge injection of 15 pC. Transition times reach 200 ns at room temperature, extending to 450 ns across the full operating range of -40 °C to +85 °C. The component utilizes a 28-pin PLCC package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the complete part number against official documentation, as suffixes define critical attributes such as packaging format and compliance status. Confirm that the specific ordering code matches the required tape and reel configuration and lead-free specifications before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when differential signal routing is required within a multiplexed architecture. Ensure the application voltage does not exceed the 44 V absolute maximum rating. Verify that the 125 Ω maximum on-resistance meets the system's signal integrity requirements under worst-case temperature conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG406/DG407 series of monolithic CMOS analog multiplexers. It serves as a functional counterpart to the DG406, which handles single-ended signals, while providing differential capabilities. The series is designed to replace legacy devices like the DG507A with improved performance metrics.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the DG407 handle input signals exceeding the power supply rails?

Signals on the source or drain pins exceeding the supply rails are clamped by internal diodes. Designers must limit the forward diode current to the maximum ratings specified in the datasheet.

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

The Enable input allows the user to reset the multiplexer so that all switches are turned off. This feature facilitates the stacking of several multiplexer devices on a single bus.

Does the device support single-supply operation?

Yes, the DG407 supports single-supply operation with a minimum voltage of 5 V and a maximum rating of 44 V, in addition to dual-supply configurations.
