Description
These standard solid state displays
have a 7.4 mm (0.29 inch) dot
matrix character and an on-board
IC with data memory latch/
decoder and LED drivers in a
glass/ceramic package.
The hermetic HDSP-078x,-079x/
-088x displays utilize a solder
glass frit seal. The HDSP-098X
displays utilize an epoxy glass-to-
ceramic seal.
The numeric devices decode posi-
tive BCD logic into characters
“0-9,” a “–” sign, decimal point,
and a test pattern. The
hexadecimal devices decode
positive BCD logic into 16
characters, “0-9, A-F.” An input is
provided on the hexadecimal
devices to blank the display (all
LEDS off) without losing the
contents of the memory.
The over range device displays
“± 1” and right hand decimal
point and is typically driven via
external switching transistors.

Mechanical
These displays are hermetically
sealed for use in environments
that require a high reliability
device. These displays are
designed and tested to meet a
helium leak rate of
5 x 10-8 cc/sec.
These displays may be mounted
by soldering directly to a printed
circuit board or insertion into a
socket. The lead-to-lead pin
spacing is 2.54 mm (0.100 inch)
and the lead row spacing is 15.24
mm (0.600 inch). These displays
may be end stacked with 2.54
mm (0.100 inch) spacing
between outside pins of adjacent
displays. Sockets such as Augat
324-AG2D (3 digits) or Augat
508-AG8D (one digit, right angle
mounting) may be used.
The primary thermal path for
power dissipation is through the
device leads. Therefore, to insure
reliable operation up to an
ambient temperature of +100°C,
it is important to maintain a
base-to-ambient thermal
resistance of less than
35°C watt/device as measured on
top of display pin 3.
For further information on
soldering and post solder
cleaning, see Application Note
1027, Soldering LED
Components.

Preconditioning
These displays are 100% pre-
conditioned by 24 hour storage at
125°C, at 100°C for the HDSP-
098x Series.
Contrast Enhancement
These display devices are
designed to provide an optimum
ON/OFF contrast when placed
behind an appropriate contrast
enhancement filter. For further
information on contrast
enhancement, see Application
Note 1015, Contrast
Enhancement for LED
Displays.
Over Range Display
The over range devices display
“±1” and decimal point. The
character height and package
configuration are the same as the
numeric and hexadecimal
devices. Character selection is
obtained via external switching
transistors and current limiting
resistors.
