Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the suffix 'T' indicates tape and reel packaging. Confirm the 'MY/PR' designation aligns with the specified wide temperature range and SOIC footprint. Cross-reference the manufacturer's latest documentation to ensure compliance with current RoHS standards and material declarations before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a wide industrial temperature range (-55°C to +125°C) is required alongside surface-mount assembly. The guaranteed 8Ω channel matching makes it suitable for precision applications where signal integrity across multiple channels is critical. Ensure the system voltage does not exceed the absolute maximum ratings to prevent permanent damage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG408/DG409 family of improved CMOS analog multiplexers. It serves as a direct replacement for legacy DIP versions while offering enhanced electrical performance metrics such as lower on-resistance and reduced charge injection.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum allowable voltage difference between V+ and V-?

The absolute maximum rating specifies that the difference between V+ and V- should not exceed +44V.

How does the device handle overvoltage conditions?

Signals exceeding V+ or V- are clamped by internal diodes. External blocking diodes can be added if power-supply sequencing cannot be guaranteed.

Is the DG408MY/PR-T pin-compatible with the original DG408?

Yes, the redesigned DG408 is a pin-compatible plug-in upgrade for the industry-standard DG408 and DG409 devices.
