Description
The HPDL-1414 and 2416 are
smart, four character, sixteensegment, 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, multiplexing 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 and 2416
incorporate many improvements
over competitive products. They
have 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 goodlooking, easy-to-use alphanumeric
display is required.
ESD WARNING: STANDARD CMOS HANDLING PRECAUTIONS SHOULD BE OBSERVED
WITH THE HPDL-1414 AND HPDL-2416.
