Description
The HPDL-1414 and 2416 are
smart, four character, sixteen-
segment, red GaAsP displays. The
HPDL-1414 has a character
height of 2.85 mm (0.112"). The
HPDL-2416 has a character
height of 4.10 mm (0.160"). The
on-board CMOS IC contains
memory, ASCII decoder, multi-
plexing 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, environment-
ally sealed unit.

ESD WARNING: STANDARD CMOS HANDLING PRECAUTIONS SHOULD BE OBSERVED
WITH THE HPDL-1414 AND HPDL-2416.
The HPDL-1414 and 2416
incorporate many improvements
over competitive products. They
have a wide operating tempera-
ture range, very fast IC access
time, and improved ESD protec-
tion. 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.
