MM5452V

Display Drivers Overview

The MM5452V is a monolithic integrated circuit utilizing CMOS metal gate, low threshold enhancement mode devices. It functions as a liquid crystal display driver capable of driving a 4½-digit 7-segment display with minimal interface requirements between the display and the data source. The device stores display data internally to reduce external logic complexity.

Display Drivers Feature Summary

• Monolithic CMOS construction using metal gate technology
• Internal storage for display data to minimize interface complexity
• Designed for direct driving of 4½-digit 7-segment LCDs

Display Drivers Applications

• Driving 4½-digit 7-segment liquid crystal displays
• Digital instrumentation requiring minimal display interface logic
• Consumer electronics with LCD readouts

Display Drivers Procurement Notes

Verify the specific package variant, as the MM5452 series includes multiple pin configurations such as 40-pin PDIP and 44-pin PLCC. Confirm that the selected part matches the required display segment count and voltage levels. Ensure compatibility with the target system's data source interface before procurement.

Display Drivers Selection Notes

Select this component when a dedicated driver for 4½-digit 7-segment LCDs is required with minimal external gating. Consider the available package options, including DIP and PLCC, based on board space and mounting preferences. Verify that the supply voltage and signal levels align with the host microcontroller or logic family.

Display Drivers Part Context

The MM5452 belongs to the National Semiconductor (now Texas Instruments) MM54xx series of liquid crystal display drivers. These components are designed to simplify the connection between digital logic sources and LCD panels by handling multiplexing and drive signals internally, reducing the need for complex external driver circuits.

Display Drivers Replacement Considerations

Check for equivalent LCD drivers from other manufacturers that support 4½-digit 7-segment displays. Verify pinout compatibility if substituting directly into existing PCB layouts. Ensure the replacement supports the same CMOS voltage ranges and display drive characteristics.
