The MM5452 is a monolithic integrated circuit utilizing CMOS metal gate, low threshold
enhancement mode devices. It is available in a 40-pin PDIP package. The chip can drive up to 32
segments of LCD and can be paralleled to increase this number. The chip is capable of driving a
4½-digit 7-segment display with minimal interface between the display and the data
The MM5452 stores display data in latches after it is clocked in, and holds the data
until new display data is received.
