play also provides internal memory for the four digits. With this
approach the user can asynchronously address one of four dig-
its and load new data without regard to the LED multiplex tim-
ing.
Figure 1 is a block diagram of the DLX1414. The device con-
sists of four (5x7) LED arrays and a single CMOS integrated
chip. The IC chip contains the column drivers and row drivers,
128 character ROM, four word x7 bit Random Access Memory,
oscillator for multiplexing, multiplex counter/decoder, cursor
memory, address decoder, and miscellaneous control logic.
This application note is intended to serve as a design and appli-
cation guide for users of the DLX1414 alphanumeric Intelligent
Display. The information presented covers device electrical
description and operation, considerations for general circuit
design, and interfacing the DLX1414 to microprocessors.
Electrical & Mechanical Description
The internal electronics of the Intelligent Display eliminates all
the traditional difficulties of using multi-digit light emitting dis-
plays (decoding, drivers and multiplexing). The Intelligent Dis-
