Description
These solid state display devices are designed and tested for use in adverse industrial environments. The character height is 7.4 mm (0.29 inch). The numeric and hexadecimal devices incorporate an on-board IC that contains the data memory, decoder and display driver functions. 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 RJA = 50C/W/ device. The device package thermal resistance is R J-PIN = 15C/W/device. The thermal resistance device pin-to-ambient through the PC board should not exceed 35C/W/device for operation at TA = +85C. 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 25C.

Notes: 4. The luminous intensity at a specific operating ambient temperature, IV (TA) may be approximated from the following exponential equation: IV (TA = IV (25C) e[k (TA - 25C)]. Device HDSP-0760 Series HDSP-0770 Series HDSP-0860 Series HDSP-0960 Series K -0.0131/C -0.0112/C -0.0104/C
5. The dominant wavelength, d, is derived from the CIE Chromaticity Diagram and is that single wavelength which defines the color of the device. 6. The HDSP-0860 and HDSP-0960 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 = 25C.

Operational Considerations
Electrical These devices use a modified 4 x 7 dot matrix light emitting diode to display decimal/hexadecimal numeric information. The high efficiency red and yellow LEDs are GaAsP epitaxial layer on a GaP transparent substrate. The green LEDs are GaP epitaxial layer on a GaP transparent substrate. 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 = 25C. Mechanical The primary thermal path for power dissipation is through the device leads. Therefore, to insure reliable operation up to an ambient temperature of +85C, it is important to maintain a caseto-ambient thermal resistance of less than 35C watt/device as measured on top of display pin 3.
For information on soldering and post solder cleaning see Application Note 1027, Soldering LED Components.
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, please refer to Application Note 1015, Contrast Enhancement Techniques 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.
