Overview
The DG408CY+ 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, guaranteed channel matching of 8Ω max, and flatness of 9Ω max. The device exhibits low charge injection (15pC max) and input off-leakage current below 5nA at +85°C. It supports rail-to-rail signal handling and provides ESD protection exceeding 2000V per MIL-STD-883 Method 3015.7.

Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure compatibility with existing PCB footprints as this component serves as a direct pin-compatible replacement for legacy designs. Confirm supply voltage requirements align with the specified operational limits before integration.
Selection Notes
Select this component when designing systems requiring high channel count multiplexing with tight resistance matching specifications. Consider the narrow SO package constraints for surface-mount applications. Evaluate thermal dissipation requirements based on the specified power derating curves for the selected operating environment.
Part Context
