DG9409EDN-T1-GE4

Overview

The DG9409EDN-T1-GE4 is a dual 4-channel differential analog multiplexer manufactured by Vishay Siliconix using BiCMOS technology. It operates on single supplies from 3 V to 16 V or dual supplies of ± 3 V to ± 8 V. The device features a typical on-resistance (RON) of 3.2 Ω, with maximum values ranging from 7.5 Ω at 12 V to 26.5 Ω at 3 V. Switching speeds include enable turn-on times up to 272 ns and turn-off times up to 104 ns depending on voltage. It provides 2500 V ESD protection and low leakage currents of 1 μA maximum. Packaged in a 16-pin QFN (4 mm x 4 mm), it supports TTL, CMOS, and LV logic interfaces.

Feature Summary

Dual 4:1 differential configuration for connecting four differential inputs to common outputs
Guaranteed break-before-make switching action to prevent momentary crosstalk
Compatible with TTL, CMOS, and low-voltage logic levels
Nickel-palladium-gold terminations compliant with JEDEC reflow standards

Applications

Automatic test equipment
Data acquisition systems
Medical and healthcare systems
Audio and video signal routing

Procurement Notes

Verify the specific suffix -E4 indicates lead-free nickel-palladium-gold terminations. Confirm the package is the 16-pin QFN variation 1. Check current availability status as distribution channels may vary. Ensure the order quantity matches the standard tape and reel packaging requirement of 2500 units per reel.

Selection Notes

Select this component when a differential multiplexing solution is required rather than single-ended switching. Verify that the supply voltage range of 3 V to 16 V aligns with system rails. Consider the 3.2 Ω typical on-resistance for signal integrity requirements. Ensure the 16-pin QFN footprint fits the PCB layout constraints.

Part Context

This part belongs to the DG9408E/DG9409E series of precision analog multiplexers. While the DG9408E offers an 8-channel single-ended configuration, the DG9409E specifically provides dual 4-channel differential switching. Both share identical fabrication technology, pinout dimensions, and electrical characteristics regarding resistance and speed.
