Overview
The DG408DY+T is an improved CMOS analog multiplexer switch manufactured by Analog Devices Inc./Maxim Integrated. It features a single 8:1 circuit configuration housed in a 16-SOIC surface-mount package. The device supports a single supply voltage range of 5V to 30V or dual supplies of ±5V to ±20V. Key electrical specifications include a maximum on-resistance of 100 ohms, a channel-to-channel matching of 1.5 ohms, and a maximum leakage current of 500pA. Switching performance is characterized by a maximum turn-on and turn-off time of 150ns each, with a propagation delay of 175ns. The component operates within a temperature range of -40°C to 85°C.
Feature Summary
- CMOS technology enables low power consumption and high-speed signal switching capabilities.
- Improved design offers enhanced on-resistance characteristics and reduced charge injection for accurate signal integrity.
- Wide operating voltage range accommodates various single and dual supply configurations.
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial process control instrumentation

Procurement Notes
Verify the specific suffix +T indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as per the latest manufacturer declaration. Ensure the ordering part number matches the exact SOIC-16 variant required for your PCB footprint. Cross-reference the datasheet revision date to confirm parameter consistency before finalizing procurement orders.
Selection Notes
Select this component when an 8:1 multiplexing function is required in a compact surface-mount format. Compare the 100-ohm on-resistance against system requirements to ensure acceptable signal attenuation. Consider the 150ns switching speed for timing constraints in your application. Verify that the 16-SOIC package dimensions fit within the available board space constraints.
Part Context
This part belongs to the DG408 series of CMOS analog multiplexers from Maxim Integrated. It serves as an improved version offering better performance metrics compared to earlier iterations. The series is designed for general-purpose analog signal switching applications where moderate speed and low power are prioritized.
Replacement Considerations
Direct substitutes include other DG408 variants such as DG408DJ+ for through-hole applications. Check for availability of DG408DY+ in tube packaging if reel quantities are not required. Ensure pin compatibility and electrical parameters match before substituting.
