8-Digit, Triplexed LCD Decoder Driver
- _- .__A.__ General Description
The MAX7231/32/33/34 family of integrated circuits
is a complete line of triplexed liquid crystal display
(LCD) drivers. These devices interface microproces-
sors (or digital systems) to multiplexed numeric and
alphanumeric displays. The MAX7231 drives 8 digits
and accepts data in a parallel format. The MAX7232
drives 10 digits and accepts data in a serial format.
Both devices feature two independent annunciators
per digit. The MAX7233 drives 4 alphanumeric 18
segment characters, The MAX7234 drives 5 alpha-
numeric 18 segment characters.
Each device includes an input butter, digit address
decoding circuitry and mask-programmed ROM
allowing six bits of input data to be decoded into
64 independent combinations of the output seg-
ments of each digit. This offloads the microprocessor
system. reducing the ROM space and CPU time
needed to service a display.
-e- Applications
These low-power LCD drivers are ideal for micro-
processor-based portable applications where power
consumption is a primary concern. Many applica-
tions also take advantage of the annunciator drive
capability, which allows unlimited variations of
display layout.
