DG408LEDN-T1-GE4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG408LEDN-T1-GE4 is an 8-channel single-ended analog multiplexer from the Vishay Siliconix DG408LE series, housed in a 16-pin QFN (3 mm x 3 mm) package. It operates on single supplies of 3 V to 16 V or dual supplies of ±3 V to ±8 V. The device features a typical on-resistance of 17 Ω and maximum leakage current of 1 nA. Key dynamic parameters include a maximum enable turn-on time of 72 ns and off-isolation of -99 dB at 100 kHz. It includes an internal regulator for low power consumption and TTL/CMOS compatible logic inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and compliance status. The 'N' suffix indicates the QFN16 package, while 'T1' denotes tape and reel packaging. Confirm RoHS compliance details directly with the supplier or datasheet as required by project specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high channel count and low on-resistance are required in a compact surface-mount footprint. Ensure the application voltage stays within the 3 V to 16 V single supply or ±3 V to ±8 V dual supply limits. Consider the QFN package thermal characteristics and exposed pad connection requirements for proper heat dissipation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG408LE family, which offers enhanced performance over standard DG408 devices. It provides lower on-resistance and improved leakage characteristics. The QFN16 package variant allows for smaller board space utilization compared to SOIC or TSSOP alternatives within the same functional family.

Analog Switches, Multiplexers, Demultiplexers FAQ

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

The Enable (EN) pin allows the user to reset all switches to the off state, which is useful for stacking several devices.

How does the device handle logic level compatibility?

All control inputs, including address and enable pins, are TTL compatible over the full specified operating temperature range.

What is the typical on-resistance value?

The typical on-resistance (RDS(on)) is 17 Ω at +12 V / ±5 V / +5 V / +3 V supplies.
