MM5483 Liquid Crystal Display Driver
General Description
The MM5483 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 31 segments of LCD and can be cascaded to
increase this number This chip is capable of driving a 4 -
digit 7-segment display with minimal interface between the
display and the data source
The MM5483 stores the display data in latches after it is
latched in and holds the data until another load pulse is
received
