DG409LDY-T1

Overview

The DG409LDY-T1 is a dual 4-channel differential analog multiplexer manufactured by Vishay Siliconix. It operates on single supplies from 2.7 V to 12 V or dual supplies of ±3 V to ±6 V. The device features a 16-pin SOIC package and supports an operating temperature range of -40 °C to +85 °C. Key electrical parameters include a typical drain-source on-resistance of 17 Ω, enable turn-on time of 38 ns, and enable turn-off time of 18 ns. Leakage current is typically 0.2 nA maximum, with charge injection at 1 pC. Power dissipation in the narrow SOIC package is rated at 600 mW.

Feature Summary

Pin-for-pin compatible with industry standard DG408 and DG409 devices
Guaranteed break-before-make switching action prevents momentary crosstalk between adjacent channels
Supports TTL, CMOS, and LV logic (3 V) compatible digital control interfaces
Provides high off-isolation of 82 dB at 1 MHz for signal integrity

Applications

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

Procurement Notes

Verify the specific suffix 'T1' indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status as indicated by the '-E3' designation if lead-free terminations are required for assembly processes. Ensure the 16-pin SOIC footprint matches the design layout constraints before finalizing procurement orders.

Selection Notes

Select this component for applications requiring low voltage operation down to 2.7 V. The DG409L variant is specifically designed for differential signal routing compared to the single-ended DG408L. Consider the 17 Ω typical on-resistance for signal loss calculations. Verify that the 600 mW power dissipation rating accommodates the thermal requirements of the target PCB environment.

Part Context

This part belongs to the DG408L/DG409L series, which are low-voltage improvements over the legacy DG408/DG409 lines. Manufactured using BiCMOS technology, these devices offer lower on-resistance, faster switching speeds, and reduced power consumption while maintaining pin compatibility with older designs.
