Overview
The DG408LDY-E3 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 typical drain-source on-resistance of 17 Ω and maximum leakage current of 1 nA at room temperature. Switching speeds feature enable turn-on times as fast as 38 ns and turn-off times of 18 ns. The component provides 82 dB off-isolation at 1 MHz and includes break-before-make switching action. It is housed in a 16-pin SOIC package.
Feature Summary
- Pin-for-pin compatibility with industry standard DG408 devices
- Guaranteed break-before-make switching to prevent crosstalk
- Low charge injection for high signal accuracy
- Compatible with TTL, CMOS, and LV logic levels
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 'E3' confirms RoHS compliance when sourcing this component. Confirm that the 'D' designation matches the required 16-pin narrow SOIC surface-mount package for your PCB layout. Ensure the operating environment stays within the -40 °C to +85 °C range specified for the D suffix variant.
Selection Notes
Select the DG408LDY-E3 over the standard DG408 when lower on-resistance and faster switching are required. This low-voltage version supports operation down to 2.7 V, making it suitable for battery-powered applications where the original 5 V minimum limit is insufficient. Verify that the 17 Ω typical resistance meets system accuracy requirements.
Part Context
This component belongs to the DG408L/DG409L series, which are low-voltage enhancements of the legacy DG408/DG409 parts. Manufactured using BiCMOS technology, these devices offer improved performance metrics including reduced power consumption and higher off-isolation compared to their predecessors while maintaining identical pinouts.

FAQ
What is the maximum analog signal range for the DG408LDY-E3?
The analog signal range extends from V- to V+, allowing signals to span the full supply voltage range provided by the user.
How does the DG408LDY-E3 handle channel switching transitions?
It utilizes a break-before-make switching action, ensuring that the previous channel disconnects before the new channel connects to eliminate momentary crosstalk.
What logic families are compatible with the control inputs?
The digital control inputs are compatible with TTL, CMOS, and Low Voltage (LV) logic families operating at 3 V.
