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.

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)].

5. The dominant wavelength, λd, is derived from the CIE chroma-
ticity diagram and represents the single wavelength which
defines the color of the device.
6. The HDSP-088X and HDSP-098X series devices are categor-
ized 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 informa-
tion. 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 MIL-STD-
883 or Class 2 of DOD-STD-1686
and DOD-HDBK-263.
