Glass/Ceramic Numeric and Hexadecimal Displays
for Industrial Applications
Data Sheet
Description
Features
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.
• Three character options Numeric, hexadecimal, over range
• Three colors; High Efficiency Red, Yellow, High Performance Green
• 4 x 7 dot matrix character
• Two high efficiency red options Low power, high brightness
• Performance guaranteed over temperature
• High temperature stabilized
• Memory latch/decoder/driver TTL compatible
• Categorized for luminous intensity
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.
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.

Iv(TA), may be approximated from the following exponential equation:
Iv(TA) = Iv(25°C) e[k(TA-25°C)].

5. The dominant wavelength, ld, is derived from the CIE chroma­ticity diagram and represents the single wavelength which defines the color of
the device.
6. The HDSP-088X and HDSP-098X series devices are categor­ized as to
dominant wavelength with the category designated by a number on the
back of the display package.
7. All typical values at VCC = 5.0 V and TA = 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 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 MILSTD-883 or Class 2 of DOD-STD-1686 and DOD-HDBK263.
Mechanical
Preconditioning
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 are 100% pre­conditioned by 24 hour
storage at 125°C, at 100°C for the HDSP-098x Series.
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.
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.
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
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.
For further information on soldering and post solder
cleaning, see Application Note 1027, Soldering LED Components.
