Overview
The DG408LDY-T1 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 values up to 80 Ω depending on conditions. Switching performance includes enable turn-on times as low as 38 ns and turn-off times of 18 ns at higher voltages. Leakage current is specified at a maximum of 1 nA, with charge injection typically at 1 pC. The component utilizes BiCMOS technology and is housed in a 16-pin SOIC package.
Feature Summary
- Pin-for-pin compatible with industry standard DG408 devices while offering improved electrical performance metrics.
- Supports both single and dual power rail configurations for flexible system integration.
- Incorporates break-before-make switching action to prevent momentary crosstalk between adjacent channels.
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 through official manufacturer documentation, as ordering suffixes may denote environmental variations. Ensure the selected variant matches the required operating temperature range of -40 °C to +85 °C for the D suffix designation.
Selection Notes
Select this component for applications requiring low voltage operation down to 3 V where standard DG408 devices may not suffice. Consider the lower on-resistance and faster switching speeds compared to legacy parts. Verify that the logic interface requirements align with the TTL, CMOS, and LV logic compatibility specifications provided in the datasheet.
Part Context
This part belongs to the DG408L/DG409L series, which are low-voltage companion devices to the established DG408/DG409 family. Manufactured using BiCMOS wafer fabrication technology, these devices provide enhanced performance characteristics including reduced power consumption and higher off-isolation compared to their predecessors.
Replacement Considerations
The DG408LDY-T1-E3 serves as the RoHS-compliant equivalent within the same package configuration. Standard DG408 devices offer pin-for-pin compatibility but lack the improved low-voltage performance specifications detailed in the DG408L datasheet.
