DG409LEDQ-T1-GE3

Overview

The DG409LEDQ-T1-GE3 is a dual 4-channel differential analog multiplexer manufactured by Vishay Siliconix. It operates on single supplies from 3 V to 16 V or dual supplies of ±3 V to ±8 V. The device connects one of four differential inputs to a common dual output using a 2-bit binary address (A0, A1). Key electrical parameters include a maximum on-resistance of 27 Ω at full temperature range, a maximum enable turn-on time of 82 ns, and a maximum enable turn-off time of 50 ns. It features low leakage current of 1 nA maximum and low parasitic capacitances. The component is housed in a 16-pin TSSOP package and supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

Break-before-make switching action prevents momentary crosstalk between adjacent channels.
Internal regulator powers the logic circuit to reduce power consumption for battery-operated applications.
TTL, CMOS, and LV logic compatible control inputs over the full specified operating temperature range.
Low off-isolation and crosstalk characteristics ensure high signal integrity.

Applications

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

Procurement Notes

Verify the specific suffix 'Q' corresponds to the TSSOP-16 package configuration required for the design. Confirm that the '-T1' designation indicates tape and reel packaging suitable for automated assembly processes. Ensure the '-GE3' suffix confirms lead-free and RoHS compliance status matches environmental regulations for the target market.

Selection Notes

Select this component when a dual differential multiplexer with low on-resistance and fast switching speeds is required. Verify that the supply voltage range of 3 V to 16 V aligns with system power rails. Consider the 16-pin TSSOP footprint for PCB layout constraints. Evaluate the 6 μA maximum power supply current for low-power portable designs.

Part Context

This part belongs to the DG409LE series, which offers pin-for-pin compatibility with the standard DG409 and DG509 devices. The LE variant specifically provides improved performance metrics such as lower on-resistance and faster switching times compared to legacy versions while maintaining identical pinouts for easy upgrades.

FAQ

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

The Enable (EN) function allows the user to reset all switches to the off state, which is useful for stacking several devices or ensuring a known initial state.

How does the device handle signals exceeding supply rails?

Signals on source, drain, address, or enable pins exceeding the power supply rails will be clamped by internal diodes. Forward diode current must be limited to maximum ratings.
