Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'TR' corresponds to the Tape and Reel packaging configuration as defined in the manufacturer's documentation. Confirm that the NiPdAu lead finish matches the requirements for the intended assembly process. Ensure the industrial temperature range of -40°C to +85°C aligns with the operational environment specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a low-jitter 4:1 differential multiplexer is required for Gigabit Ethernet or Fiber Channel applications. It is suitable for designs needing flexible input interfacing through internal termination. Consider alternative models like the SY89547L if dual outputs are necessary. Verify power supply constraints match the 3.3V requirement.
