Notes:

1. The nominal thermal resistance of a display mounted in a socket that is soldered onto a printed circuit board is

Rθ_JA= 50°C/W/device. The device package thermal resistance is Rθ_J-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 T_A= +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.

4. The luminous intensity at a specific operating ambient

temperature, I_v(T_A), may be approximated from the following

5. The dominant wavelength, λ_d, is derived from the CIE chroma-

ticity diagram and represents the single wavelength which

defines the color of the device.

exponential equation: I_v(T_A) = I_v(25°C) e^{[k(T -25°C)]}

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.

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 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 T_A= 25°C.

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

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 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

508-AG8D (one digit, right angle

mounting) may be used.

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

These displays are 100% pre-

conditioned by 24 hour storage at

125°C, at 100°C for the HDSP-

098x Series.

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

5 x 10^-8cc/sec.

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

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

soldering and post solder

cleaning, see Application Note

324-AG2D (3 digits) or Augat

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.
