Notes: 1. Operation above 85°C ambient is possible provided the following conditions are met. The junction temperature should not exceed 125°C TJ and the case temperature (as measured at pin 1 or the back of the display) should not exceed 100°C TC . 2. The HDSP-2301/-2302/-2303 HDSP-2301/-2302/-2303 should be derated linearly above 37°C at 16.7 mW/°C. This derating is based on a device mounted in a socket having a thermal resistance from case to ambient at 35°* C/W per device. See Figure 2 for power deratings based on a lower thermal resistance. 3.

Notes: 4. The characters are categorized for luminous intensity with the intensity category designated by a letter code on the bottom of the package. 5. The HDSP-2301/-2303 HDSP-2301/-2303 are categorized for color with the color category designated by a number code on the bottom of the package. 6. Ti refers to the initial case temperature of the device immediately prior to the light measurement. 7. Dominant wavelength d, is derived from the CIE chromaticity diagram, and represents the single wavelength which defines the color of the device. 8. The luminous sterance of the LED may be calculated using the following relationships: Lv (cd/m2) = lv (Candela)/A (Metre)2 Lv (Footlamberts) = i v (Candela)/A (Foot) 2 A = 5.3 x 10 ­8 M2 = 5.8 x 10­7 (Foot) 2 3 5 1/fMAX. tW tTHL 2.4 V CLOCK 90 % 1.5 V 1.5 V 1.5 V 1.5 V 10 % 0.4 V tHOLD PARAMETER tSETUP 2.4 V DATA IN 1.5 V 1.5 V 1.5 V tPLH, tPHL PROPAGATION DELAY CLOCK TO DATA OUT 1.5 V 0.4 V tSETUP CONDITION MIN.

Each four character display module features Data In and Data Out terminals arrayed for easy PC board interconnection. Data Out represents the output of the 7th bit of digit number 4 shift register. Shift register clocking occurs on the high to low transition of the Clock input. The like columns of each character in a display cluster are tied to a single pin. Figure 5 is the block diagram for the displays. High true data in the shift register enables the output current mirror driver stage associated with each row of LEDs in the 5 x 7 diode array.

Contrast Enhancement Filters. Polaroid HNCP10 HNCP10 7 is loaded into the 7 on-board shift register locations 1 through 7. Column 1 data for digits 3, 2, and 1 is similarly shifted into the display shift register locations. The column 1 input is now enabled for an appropriate period of time, T. A similar process is repeated for columns 2, 3, 4, and 5. If the time necessary to decode and load data into the shift register is t, then with five columns, each column of the display is operating at a duty factor of: D.F. = T 5 (t + T) The time frame, t + T, allotted to each column of the display is generally chosen to provide the maximum duty factor consistent with the minimum refresh rate necessary to achieve a flicker free display. For most strobed display systems, each column of the display should be refreshed (turned on) at a minimum rate of 100 times per second. With columns to be addressed, this refresh rate then gives a value for the time t + T of: 1/[5 x (100)] = 2 msec If the device is operated at 3.0 MHz clock rate maximum, it is possible to maintain t
