DG408LDY-T1-E3

Overview

The DG408LDY-T1-E3 is an eight-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 based on a 3-bit binary address (A0, A1, A2). Key electrical parameters include a typical drain-source on-resistance of 17 Ω and maximum leakage current of 1 nA at room temperature. Switching speeds feature a turn-on time of 38 ns and turn-off time of 18 ns. It utilizes BiCMOS technology for low power consumption and high accuracy.

Procurement Notes

Verify the component against official Vishay datasheet specifications before integration. Confirm that the SOIC-16 package variant matches your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power rails. Validate RoHS compliance status if required by your manufacturing standards. Cross-reference the ordering suffix to confirm the specific reel packaging configuration.

Selection Notes

Select this component when requiring low on-resistance and fast switching in a compact surface-mount package. Consider the DG409L if differential input handling is necessary instead of single-ended signals. Evaluate the power dissipation limits relative to your ambient temperature conditions. Verify logic level compatibility with your microcontroller or FPGA outputs. Check if the lower voltage operation range suits your battery-powered applications better than higher voltage alternatives.

Part Context

This part belongs to the DG408L/DG409L series, which are low-voltage enhancements of the legacy DG408/DG409 multiplexers. Manufactured using BiCMOS wafer fabrication technology, these devices offer improved performance metrics including reduced on-resistance and faster switching times compared to their predecessors. The series is designed for applications demanding high accuracy and simple logic interfacing.
