HDSP-078x
Glass/Ceramic Numeric and Hexadecimal Displays
for Industrial Applications
Data Sheet
HDSP-078x, HDSP-079x
HDSP-088x, HDSP-098x
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 positive 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.
Features
• Three character options
Numeric, hexadecimal, over range
• Three colors
High Efficiency Red, Yellow, High Performance Green
• 4 x 7 dot matrix character
• High Efficiency Red, Yellow and High Performance
Green
• Two high efficiency red options

• Categorized for luminous intensity
The over range device displays “±1” and right hand
decimal point and is typically driven via external
switching transistors.

Notes:
1. The nominal thermal resistance of a display mounted in a socket that is soldered onto a printed circuit board is RqJA = 50°C/W/device. The device
package thermal resistance is RqJ-PIN = 15°C/W/device. The thermal resistance device pin-to-ambient through the PC board should not exceed
35°C/W/device for operation up to TA = +100°C.
2. Voltage values are with respect to device ground, pin 6.
3. These displays are categorized for luminous intensity with the intensity category designated by a letter code located on the back of the display
package. Case temperature of the device immediately prior to the light measurement is equal to 25°C.

Operational Considerations
Electrical
These devices use a modified 4 x 7
dot matrix of light emitting diodes
to display decimal/hexadecimal
numeric information. The high
efficiency red and yellow displays
use GaAsP/GaP LEDs and the
high performance green displays
use GaP/GaP LEDs. The LEDs are
driven by constant current
drivers, BCD information is
accepted by the display memory
when the enable line is at logic
low and the data is latched when

Notes:
4. The luminous intensity at a specific operating ambient temperature,
Iv(TA), may be approximated from the following exponential equation:
Iv(TA) = Iv(25°C) e[k(TA-25°C)].

Min.
the enable is at logic high. Using
the enable pulse width and data
setup and hold times listed in the
Recommended Operating
Conditions allows data to be
clocked into an array of displays
at a 6.7 MHz rate.
The decimal point input is active
low true and this data is latched
into the display memory in the
same fashion as the BCD data.
The decimal point LED is driven
by the on-board IC.
The blanking control input on the
hexadecimal displays blanks
(turns off) the displayed
information without disturbing
the contents of display memory.
The display is blanked at a
minimum threshold level of
2.0 volts. When blanked, the
display standby power is
nominally 250 mW at TA = 25°C.
The ESD susceptibility of the IC
devices is Class A of MIL-STD-883
or Class 2 of DOD-STD-1686 and
DOD-HDBK-263.
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.
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.
For further information on
soldering and post solder
cleaning, see Application Note
1027, Soldering LED
Components.
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.
Preconditioning
These displays are 100% preconditioned by 24 hour storage
at 125° C, at 100° C for the
HDSP-098x Series.
