Display Drivers Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the 44-pin PLCC footprint matches the target PCB layout. Ensure the design accommodates the specified 4.75 V to 11 V operating voltage range. Check for RoHS compliance status if required by assembly standards. Validate that the serial interface timing aligns with the host controller specifications.
Display Drivers Selection Notes
Select this component for applications requiring dedicated alphanumeric LED driving without multiplexing complexity. Consider the 15 mA output capability for standard LED segment requirements. Evaluate the serial interface needs against available microcontroller resources. Compare thermal performance within the -40°C to +85°C range against environmental conditions. Assess the 44-pin package availability against board space constraints.
Display Drivers Part Context
This part belongs to the MM5450/5451 family of LED display drivers from Microchip Technology. It shares core functionality with the MM5450 but lacks the enable pin feature found in the MM5450 variant. Both devices utilize the same N-channel metal-gate technology. The MM5451 series is designed for straightforward alphanumeric display applications requiring reliable segment control.
