DG408DJ-E3

Overview

The DG408DJ-E3 is an 8-channel single-ended analog multiplexer manufactured by Vishay Siliconix. It connects one of eight inputs to a common output using a 3-bit binary address (A0, A1, A2). The device operates on a single supply from +5 V to +36 V or dual supplies from ±5 V to ±20 V. Key electrical parameters include a maximum drain-source on-resistance of 100 Ω, a transition time of 160 ns, and a charge injection of 20 pC. It features TTL-compatible logic inputs and an enable function for stacking multiple devices. The component is housed in a 16-pin plastic DIP package and supports an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Break-before-make switching action prevents momentary crosstalk between adjacent channels.
• TTL-compatible control inputs allow direct interfacing with standard digital logic.
• Enable function resets all switches to the off state for multi-device stacking.

Applications

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

Procurement Notes

Verify the specific suffix 'E3' confirms lead-free and RoHS compliance status as defined in the manufacturer's ordering information. Confirm that the PDIP-16 package matches the required through-hole mounting specifications for the target PCB layout. Ensure the absolute maximum voltage ratings are not exceeded during operation.

Selection Notes

Select this component when an 8:1 single-ended multiplexing configuration is required within a 16-pin footprint. Verify that the 100 Ω maximum on-resistance meets the signal integrity requirements of the application. Confirm compatibility with the available single or dual power supply voltages before finalizing the design.

Part Context

This part belongs to the DG408/DG409 family of high-performance CMOS analog multiplexers. The DG408 variant specifically provides an 8-channel single-ended architecture, whereas the DG409 offers a dual 4-channel differential configuration. Both share similar electrical characteristics and packaging options within the same product line.

FAQ

How does the DG408 prevent crosstalk between channels?

It utilizes break-before-make switching action, which ensures that the previous channel disconnects before the new channel connects, preventing momentary crosstalk.

What is the maximum analog signal range?

The analog signal range extends from V- to V+, allowing signals up to the power supply rails.

Can multiple DG408 devices be stacked?

Yes, the Enable (EN) function allows the user to reset the multiplexer to all switches off, facilitating the stacking of several devices.
