HPDL-1414
Four Character Smart Alphanumeric Displays
Data Sheet
Description
The HPDL-1414 is a smart, four character, sixteen-
segment, red GaAsP display. The HPDL-1414 has a
character height of 2.85 mm (0.112"). The on-board
CMOS IC contains memory, ASCII decoder, multiplex-
ing circuitry and drivers. The monolithic LED characters
are magnified by an immersion lens which increases
both character size and luminous intensity. The
encapsulated dual-in-line package provides a rugged,
environmentally sealed unit.
The HPDL-1414 incorporates many improvements
over competitive products. It has a wide operating
temperature range, very fast IC access time, and
improved ESD protection. The displays are also fully
TTL compatible, wave solderable, and highly reliable.
These displays are ideally suited for industrial and
commercial applications where a good-looking, easy-
to-use alphanumeric display is required.
