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

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 re-

ceived.

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.
