Description
These are 3.7 mm (0.145 inch)
four character 5 x 7 dot 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.
The address and data inputs can
be directly connected to
microprocessor address and data
buses.
Devices
AlGaAs Red
HDLS-1414 (sun. view.)
HDLU-1414 (low power)
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.
High Efficiency Red
HDLO-1414

HDLA-1414
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 LED to a
much lower level, and maintains
an intensity comparable to the
HDLO-1414.

ESD Warning: Standard CMOS Handling Precautions should be observed with
the HDLX-1414.
