General Description
The MM5452 is a monolithic integrated circuit utilizing
CMOS metal gate low threshold enhancement mode devic-
es It is available in a 40-pin molded 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 4
digit 7-segment display with minimal interface between the
display and the data source
The MM5452 stores display data in latches after it is
clocked in and holds the data until new display data is re-
ceived
