Overview
The DG408DY is an improved CMOS analog multiplexer featuring a 1-of-8 configuration in a 16-pin Narrow SO package. It operates with single supplies from +5V to +30V or dual supplies from ±5V to ±20V. Key electrical parameters include a maximum on-resistance of 100Ω, channel matching of 8Ω max, and on-resistance flatness of 9Ω max. Charge injection is guaranteed at 15pC max, while input leakage remains below 5nA at +85°C. The device supports rail-to-rail signal handling and includes ESD protection exceeding 2000V per MIL-STD-883 Method 3015.7.
Feature Summary
- Pin-compatible plug-in upgrade for industry standard DG408/DG409
- Guaranteed low charge injection and low on-resistance
- Rail-to-rail signal handling capability
- Digital inputs compatible with TTL and CMOS logic
Applications
- Sample-and-Hold Circuits
- Test Equipment
- Guidance and Control Systems
- Communications Systems
- Data-Acquisition Systems
- Audio Signal Routing
Procurement Notes
Verify the specific suffix 'DY' corresponds to the -40°C to +85°C temperature range and Narrow SOIC package when sourcing. Confirm manufacturer documentation for current production status, as legacy CMOS parts may face obsolescence. Ensure supply voltage sequencing follows recommended practices to prevent latch-up during power-up.
Selection Notes
Select this component for applications requiring high channel count (8:1) with tight resistance matching. Verify that the 100Ω on-resistance meets system loss requirements. Consider the 15pC charge injection limit for precision data-acquisition tasks. Ensure the 16-pin Narrow SO footprint fits the PCB layout constraints compared to DIP alternatives.
Part Context
Part of the Maxim Integrated DG408/DG409 family of improved CMOS analog multiplexers. Designed as direct replacements for older industry-standard versions with enhanced performance metrics including lower leakage and better channel matching. Manufactured by Analog Devices Inc./Maxim Integrated.

FAQ
What is the maximum charge injection for the DG408DY?
The maximum charge injection is guaranteed to be 15pC.
Does the DG408DY support single-supply operation?
Yes, it operates with a single supply ranging from +5V to +30V.
How does the DG408DY handle overvoltage conditions?
It features internal diode clamping on digital inputs and switches, but external blocking diodes are recommended if power-supply sequencing cannot be guaranteed.
