Procurement Notes

Verify the complete part number including the RL suffix to confirm reel packaging specifications. Ensure compatibility with SOIC-16 footprint requirements during PCB layout. Confirm that the integrated DC/DC converter output meets the target circuit's voltage regulation needs. Check for any specific handling instructions related to moisture sensitivity levels before assembly.

Selection Notes

Select this component when high channel density and integrated isolation power are required. The 5kVrms rating suits applications demanding significant potential differences between circuits. Consider the 25 Mb/s speed limit for timing-critical designs. Evaluate thermal management strategies given the 400 mW power dissipation constraint in enclosed environments.
