MM145453
Liquid Crystal Display Driver
General Description
The MM145453 is a monolithic integrated circuit utilizing
CMOS metal gate, low threshold enhancement mode de-
vices. The chip can drive up to 33 LCD segments and can be
paralleled to increase this number. The chip is capable of
driving a 4
1
digit 7-segment display with minimal interface
2
between the display and the data source.
The MM145453 stores display data in latches after it is
clocked in, and holds the data until new display data is
received.
The MM145453 is available in a molded 44 pin surface
mount PLCC package. The MM145453 is pin out and func-
tionally compatible with the MC145453.
