1 DSP-078x, DSP-079x, DSP-088x, DSP-098x Glass/Ceramic Numeric and exadecimal Displays for Industrial Applications Data Sheet 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 ED drivers in a glass/ ceramic package. The hermetic DSP-078x,-079x/ 088x displays utilize a solder glass frit seal. The DSP-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 EDS 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 Rq JA = 0 C/W/device. The device package thermal resistance is Rq J-PIN = 1 C/W/device. The thermal resistance device pin-to-ambient through the PC board should not exceed 3 C/ W/device for operation up to T A = +100 C. 2. Voltage values are with respect to device ground, pin 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 2 C. 4

The luminous intensity at a specific operating ambient temperature, I v (T A ), may be approximated from the following exponential equation: I v (T A ) = I v (2 C) e [k(ta-2 C)]. Device DSP-078 Series DSP-079x Series DSP-088x Series DSP-098x Series K / C / C / C. The dominant wavelength, l d, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device. 6. The DSP-088X and DSP-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 V CC =.0 V and T A = 2 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 EDs and the high performance green displays use GaP/GaP EDs. The EDs 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 Mz 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 ED 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 20 mw at T A = 2 C. The ESD susceptibility of the IC devices is Class A of MI- STD-883 or Class 2 of DOD-STD-1686 and DOD-DBK- 263.

6 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 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 2.4 mm (0.100 inch) and the lead row spacing is 1.24 mm (0.600 inch). These displays may be end stacked with 2.4 mm (0.100 inch) spacing between outside pins of adjacent displays. Sockets such as Augat 324-AG2D (3 digits) or Augat 08-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 3 C watt/device as measured on top of display pin 3. Preconditioning These displays are 100% preconditioned by 24 hour storage at 12 C, at 100 C for the DSP-098x Series. 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 101, Contrast Enhancement for ED 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. For further information on soldering and post solder cleaning, see Application Note 1027, Soldering ED Components.
