HDLX-1414 Series

Four Character Smart Alphanumeric Displays

Data Sheet

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

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

pinforpincompatiblewiththeHPDL-1414.TheICstoresand

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.
