DG9408DN-T1-E4

Overview

The DG9408DN-T1-E4 is an 8-channel single-ended analog multiplexer manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 2.7 V to 12 V or dual supplies of ±3 V to ±6 V. The device connects one of eight inputs to a common output via a 3-bit binary address (A0, A1, A2). Key electrical parameters include a maximum on-resistance of 25.5 Ω at 3 V and 7.5 Ω at 12 V, with a typical value of 3.9 Ω. Switching characteristics feature a maximum transition time of 182 ns at 3 V and 71 ns at 12 V. The component utilizes BiCMOS technology, offers break-before-make switching, and provides 2000 V ESD protection.

Feature Summary

• Supports both single and dual power supply configurations for flexible system integration.
• Incorporates break-before-make switching action to prevent momentary crosstalk between adjacent channels.
• Features low leakage current and high off-isolation for signal integrity preservation.
• Compatible with TTL, CMOS, and LV logic levels across the operating voltage range.

Applications

• Data acquisition systems
• Battery operated equipment
• Portable test equipment
• Sample and hold circuits
• Audio and video signal routing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to ensure correct package and termination specifications. Confirm that the required lead-free terminations meet project standards. Check for any recent product change notices regarding manufacturing locations or material compliance updates before finalizing procurement plans.

Selection Notes

Select this component when an 8-channel single-ended multiplexing function is required within a low-voltage environment. Ensure the application voltage falls within the 2.7 V to 12 V single-supply range. Verify that the logic interface matches the available control signals, as the device supports TTL, CMOS, and LV logic compatibility.

Part Context

This part belongs to the DG940x series of precision low-voltage analog multiplexers. It shares functional similarities with the DG9409, which offers a dual 4-channel differential configuration. Both devices utilize the same QFN-16 package and BiCMOS fabrication technology, allowing for interchangeable mechanical design in compatible applications.

Replacement Considerations

The DG9409 serves as a functional alternative within the same family but provides a dual 4-channel differential configuration instead of 8 single-ended channels. Designers must verify pinout compatibility and channel count requirements when considering substitution.
