Triplexed LCD Decoder/Drivers
- - - - 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 Ticropr.oces-,
sors (or digi.tal 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 buffer, 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.
. i 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.
