Display Drivers Procurement Notes

Verify the specific suffix, such as NOPB, against official documentation to confirm exact specifications. Note that this product line may be discontinued or subject to manufacturing phase-outs. Confirm availability status directly with authorized distributors before finalizing procurement plans.

Display Drivers Selection Notes

Select this component for applications requiring direct drive of segmented LCDs without external load signals. Ensure the design accommodates the 40-pin DIL footprint and the specified voltage requirements. Verify thermal management capabilities given the 350 mW power dissipation limit in the target enclosure.

Display Drivers Part Context

This part belongs to the MM5453 series of display drivers. It is distinct from the MM5452 variant which includes a Data Enable pin. The MM5453N specifically denotes the through-hole DIP version, differing from surface-mount options like the PLCC-44 package found in other variants.
