DG408DY-T1-E3

Overview

The DG408DY-T1-E3 is an 8-channel single-ended analog multiplexer manufactured by Vishay Siliconix in a 16-pin narrow SOIC surface-mount package. It connects one of eight inputs to a common output via a 3-bit binary address (A0, A1, A2). The device operates on a single supply voltage ranging from +5 V to +36 V or dual supplies from ±5 V to ±20 V. Key electrical specifications include a maximum drain-source on-resistance of 100 Ω, a transition time of 160 ns, and charge injection of 20 pC. It features TTL-compatible logic inputs and break-before-make switching action.

Feature Summary

• Break-before-make switching action prevents momentary crosstalk between adjacent channels.
• TTL-compatible control inputs ensure compatibility across the full operating temperature range.
• Enable function allows resetting all switches to the off state for stacking multiple devices.
• Epitaxial layer design prevents latchup under specified operating conditions.

Applications

• High-speed data acquisition systems
• Audio signal switching and routing
• Automated test equipment (ATE) systems
• Avionics applications

Procurement Notes

Verify the specific suffix 'T1' confirms tape-and-reel packaging rather than tube packaging when sourcing components. Confirm the '-E3' designation indicates lead-free and RoHS compliance status as required by project specifications. Ensure the manufacturer source matches Vishay Siliconix documentation to validate the part number authenticity and revision level.

Selection Notes

Select this component for designs requiring high-performance CMOS analog multiplexing with low power dissipation. Verify that the 100 Ω maximum on-resistance meets the signal path requirements. Ensure the 16-pin SOIC footprint aligns with the PCB layout constraints. Consider the 160 ns transition time for timing-sensitive signal routing applications.

Part Context

This component belongs to the DG408/DG409 family of high-performance CMOS analog multiplexers. The DG408 variant specifically provides an 8:1 configuration, whereas the DG409 offers a dual 4:1 differential configuration. Both share similar electrical characteristics and are designed using a 44 V silicon-gate CMOS process for extended voltage ratings.

FAQ

What is the maximum absolute voltage rating for the DG408?

The absolute maximum voltage rating from V+ to V- is 44 V, extended by the 44 V silicon-gate CMOS process.

How does the Enable (EN) pin function affect the switch states?

Driving the EN pin low resets the multiplexer to turn all switches off, which is useful for stacking several devices together.

What is the typical charge injection value for this device?

The typical charge injection is 20 pC, measured with a load capacitance of 10 nF and VS at 0 V.
