Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number against official manufacturer documentation before procurement. Confirm that the suffix 'ECTJ' corresponds to the specific tape-and-reel packaging and temperature grade required for your design. Ensure compatibility with standard 32-TQFN footprints during PCB layout. Cross-reference RoHS compliance status using current datasheets as regulatory requirements may evolve over time.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low-loss signal switching for Gigabit Ethernet applications. The 5.5-ohm maximum on-resistance minimizes signal attenuation across the switching path. Verify that the 3V to 3.6V supply voltage aligns with your system's power rails. Consider the 32-TQFN package dimensions for thermal management and board space constraints in dense layouts.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX4890 family of Ethernet switches developed by Maxim Integrated, now part of Analog Devices.
