Description
Features
Theseare3.7mm(0.145inch)fourcharacter5x7dot
matrix displays driven by an on-board CMOS IC.
These displays are pin for pin compatible with the
HPDL-1414. The IC stores and decodes 7-bit ASCII
data and displays it in an easy to read
5 x 7 font. Multiplexing and LED drive circuitry is
also included in the display, and fast setup and hold
times allow it to interface easily with common
microprocessors.
• Dot matrix replacement of HPDL-1414
• Smart alphanumeric display
Built-in RAM, ASCII decoder, and LED drive circuitry
• 128 ASCII character set
• End stackable
• Categorized for luminous intensity; Yellow and Green
categorized for color
• Low power and sunlight viewable AlGaAs versions
• Wide viewing angle (50° typical)
Theaddressanddatainputscanbedirectlyconnected
to microprocessor address and data buses.
The HDLX-1414 offers a larger character set than the
HPDL-1414. Lower case letters and special symbols
are now offered, made possible by the
5 x 7 dot matrix character layout.
The difference between the sunlight viewable HDLS-
1414 and the low power HDLU-1414 lies in the
brightness level. The sunlight viewable version is
internally set to provide high intensity characters.
The low power version uses the same bright LED
technology, but reduces the current through each
LEDtoamuchlowerlevel,andmaintainsanintensity
comparable to the HDLO-1414.

Description
The HDLX-1414 is a 12-pin DIP
package that can be stacked to
create a character array of any
size. The display is designed to
operate reliably in –40˚C to
+85˚C ambient temperatures.

results, standard CMOS handling
precautions should be used.
Prior to use, the HDLX-1414
should be stored in antistatic
tubes or conductive material.
During assembly a grounded
conductive work area should be
used, and assembly personnel
should wear conductive wrist
straps. Lab coats made of
synthetic material should be
avoided since they are prone to
static charge build-up. Input
current latchup can be caused
when the CMOS inputs are
subjected either to a voltage
