Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'MI' corresponds to the industrial temperature range (-40°C to +85°C) and MLF-32 package configuration as documented in the official datasheet. Confirm that the 'TR' suffix indicates tape and reel packaging. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a dual 2:1 multiplexer with low jitter and internal termination is required for 2.5V systems. Consider the SY89543L if a 3.3V supply is necessary instead of the standard 2.5V operation. Evaluate the SY89544U or SY89546U if four differential inputs are needed rather than two. Ensure the application requires LVDS output swing characteristics and CMOS/TTL control logic compatibility.
