The hermetic HDSP-078x,-079x/ -088x displays utilize a solder glass frit seal. The HDSP-098X displays utilize an epoxy glass-toceramic 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.

The nominal thermal resistance of a display mounted in a socket that is soldered onto a printed circuit board is RθJA = 50°C/W/device. The device package thermal resistance is RθJ-PIN = 15°C/W/device. The thermal resistance device pin-toambient 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. 4 Electrical/Optical Characteristics TA = –55°C to +100°C Description Supply HDSP-078x Series Current HDSP-079x/-088x/ -098x Series Power HDSP-078x Series Dissipation HDSP-079x/-088x/ -098x Series Logic, Enable and Blanking Low-Level Input Voltage Logic, Enable High-Level Input Voltage Blanking High-Voltage; Display Blanked Logic and Enable Low-Level Input Current Blanking Low-Level Input Current Logic, Enable and Blanking High-Level Input Current Weight Leak Rate Symbol ICC PT VIL Test Conditions VCC = 5.5 V Characters “5.” or “B” displayed VCC = 5.5 V Characters “5.” or “B” displayed VCC = 4.5 V Max. 105 120 175 390 573 690 963 0.8 Unit mA mW V 2.0 V VBH 2.3 V IIL VCC = 5.5 V –1.6 mA IBL IIH VIL = 0.4 V VCC = 5.5 V VIH = 2.4 V –10 +40 µA µA 5 x 10-8 gm cc/sec 1.0 Device K HDSP-078 Series HDSP-079x Series –0.0131/°C HDSP-088x Series –0.0112/°C HDSP-098x Series –0.0104/°C 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 Typ.[7] 78 VIH 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)]. Operational Considerations Min. 5. The dominant wavelength, λd, 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. 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-STD883 or Class 2 of DOD-STD-1686 and DOD-HDBK-263. 5 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. 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. 6 Package Dimensions Character + – 1 Decimal Point Blank 1 1 0 X X 0 Pin 2,3 X X 1 X 0 4 X X X 1 0 Notes: 0: Line switching transistor in Figure 7 cutoff. 1: Line switching transistor in Figure 7 saturated.
