MM145453

MM145453 Liquid Crystal Display Driver December 1999 MM145453 Liquid Crystal Display Driver General Description The MM145453 is a monolithic integrated circuit utilizing CMOS metal gate, low threshold enhancement mode devices. The chip can drive up to 33 LCD segments and can be paralleled to increase this number. The chip is capable of driving a 41⁄2 digit 7-segment display with minimal interface 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 functionally compatible with the MC145453.
