Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS standards during procurement. Confirm the SOIC-16 package dimensions match the design footprint requirements. Ensure the operating voltage aligns with the 2 V to 6 V specification. Check for moisture sensitivity levels if the component requires reflow soldering processes. Validate that the manufacturer source provides official datasheets for technical reference.

Selection Notes

Select this component when a 4-by-4 register file is required with high-speed CMOS performance. The wide supply voltage range offers flexibility compared to standard 5 V only devices. Consider the SOIC-16 package for surface-mount assembly needs. Evaluate the propagation delay against system timing constraints. Verify compatibility with existing logic families in the circuit design.
