DG408LEDQ-T1-GE3

Overview

The DG408LEDQ-T1-GE3 is an eight-channel single-ended analog multiplexer from Vishay Siliconix, housed in a 16-pin TSSOP 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. Power consumption is limited to 6 μA with the enable pin active. Switching times include a turn-on time of 55 ns and turn-off time of 36 ns at ±5 V. It includes break-before-make switching and TTL/CMOS compatible logic inputs.

Feature Summary

• Eight-channel single-ended multiplexing controlled by three-bit binary address
• Internal voltage regulator for low power consumption and battery operation
• Break-before-make switching action to prevent momentary crosstalk
• TTL, CMOS, and LV logic compatibility across full temperature range

Applications

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

Procurement Notes

Verify the ordering suffix -T1 indicates tape and reel packaging containing 3000 units. Confirm the -GE3 suffix denotes lead-free and RoHS compliance. Ensure the specific TSSOP-16 package variant matches the design requirements. Cross-reference the document number 78084 for the latest specifications.

Selection Notes

Select this component for applications requiring low on-resistance and fast switching speeds within a wide voltage range. The internal regulator reduces external power demands. Verify that the 16-pin TSSOP footprint fits the PCB layout. Consider the 6 μA supply current for strict power budget constraints.

Part Context

This part belongs to the DG408LE series, which offers enhanced performance over standard DG408 devices. It provides improved operating voltage ranges up to 16 V and lower switch on resistance. The series maintains pin-for-pin compatibility with legacy DG408 and DG508 parts.

FAQ

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

The Enable pin allows the user to reset all switches to the off state, facilitating the stacking of several devices.

How does the device handle channel switching?

It utilizes a break-before-make switching action to protect against momentary crosstalk between adjacent channels during transitions.

Is the device suitable for single-supply operation?

Yes, it supports single supply voltages ranging from 3 V to 16 V as well as dual supplies from ±3 V to ±8 V.
