DG408LDQ-E3

Overview

The DG408LDQ-E3 is an 8-channel single-ended analog multiplexer manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 3 V to 12 V or dual supplies of ± 3 V to ± 6 V. The device features a typical drain-source on-resistance (RDS(on)) of 17 Ω and maximum leakage current of 1 nA at room temperature. Enable turn-on time is typically 38 ns, with off-time at 18 ns. Charge injection is limited to 1 pC. It utilizes BiCMOS technology for low power consumption and high accuracy. The component is housed in a 16-lead TSSOP package and supports operation across a temperature range of -40 °C to +85 °C.

Feature Summary

Pin-for-pin compatibility with industry standard DG408 devices
Guaranteed break-before-make switching action to prevent crosstalk
TTL, CMOS, and LV logic compatible interfaces
High ESD protection rating of 2000 V via human body model

Applications

Data acquisition systems
Battery operated equipment
Portable test equipment
Sample and hold circuits
Communication systems

Procurement Notes

Verify the specific suffix 'E3' indicates RoHS compliance when sourcing this component. Confirm the 'D' suffix corresponds to the -40 °C to +85 °C operating temperature range required for your application environment. Ensure the LDQ designation matches the 16-lead TSSOP package footprint needed for your PCB layout design.

Selection Notes

Select the DG408LDQ-E3 over standard DG408 variants when lower on-resistance and faster switching speeds are critical. This low-voltage version is suitable for applications requiring operation below 5 V. Verify that the 16-lead TSSOP package dimensions fit within the available board space constraints of the target electronic assembly.

Part Context

This component belongs to the DG408L/DG409L family of precision analog multiplexers. It serves as a low-voltage companion to the legacy DG408 series, offering improved performance metrics while maintaining identical pin configurations. The DG408L specifically handles single-ended signals, whereas its counterpart manages differential inputs.
