HDLX-1414 Series
Four Character Smart Alphanumeric Displays
Data Sheet
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.
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
LED to a much lower level, and maintains an intensity
comparable to the HDLO-1414.
